      [PATCH] kNFSd cleanup of nfsd_open · 10e3215f
      Christoph Hellwig authored
      This patch makes nfsd_open use init_private_file to initilize
      the file pointer the caller had allocated on stack.  In addition
      a number of small cleanups:
      
       - format comments to be readable on 80char ANSI terminal
       - don't fop_get (and fop_put in nfsd_close), out file already
         is a reference to the inode so they can't go away.
       - don't decrement f_count on failure - it won't be checked anyway
       - don't check for filp->f_op n nfsd_close, it can't be NULL

      [PATCH] Initial md/raid5 support for 2.5 (with bio) · 313d90b7
      Neil Brown authored
      With this patch raid5 works.  There is still some more
      work to though.
      
      - uses bio instead of buffer_head
      - stripe cache is now a fixed size.
         If read requests are smaller, we read the whole block anyway
         If write reqeusts are smaller, we pre-read.
      - stripe_head is now variable sized with an array of structures at
        the end.  We allocate extra space depending on how many devices
        are in the array.
        stripe_head has it's very own slab cache.
      - store and use bdev for each device in array
      
      by-passing the cache for reads is currently disabled.  I need to
      think through the implications (and implementation) of allowing
      large bion that are larger than the stripe cache to go directly
      to the device (if it isn't failed of-course).

      Neil Brown authored
      - remove md_ prefix from some calls that used to be

      - remove "raid5_" prefix from some static functions,
        in line with recent changes to raid1.c
      
      ?? should cpu_has_mmx be moved to in processor.h ?

      [PATCH] Change MD Superblock IO to go straight to submit_bio · bd415ca2
      Neil Brown authored
      The current code hits the page cache for the block device
      which requires memory allocation which can sometimes cause
      a deadlock (if it blocks the raid5d thread).
      
      This code takes the page that holds the superblock, and
      passes it to submit_bh in a suitable bio wrapper.

      [PATCH] Increase snd buffer size for UDP · b51682c0
      Neil Brown authored
      I under-allocated the space that RPC needs for transmit on a UDP
      socket.   We need lots of space to be allowed (though we may not use
      much) so that a lack of un-commited transmit space will not cause new
      requests to be blocked.

      [PATCH] cleanup read/write · ff59bcd2
      Christoph Hellwig authored
      Currently sys_read/sys_pread and sys_write/sys_pwrite basically contain
      lots of duplication of the same checks/code.
      
      This moves all that into vfs_read/vfs_write helpers that have the same
      prototypes as the read/write file operations.  In addition I have
      choosen to export these interfaces to module so people doing inkernel
      file reading/writing can use these instead of duplicating the checks
      (which is very likely to be done wrong).

      [PATCH] Thread group exit problem reappeared · 3bfae933
      Dave McCracken authored
      A long time ago there was thread group code that at exit time tried to
      reparent a task to another task in the thread group.  I discovered a major
      race condition in this code, and submitted a patch that removed it.  This
      patch was accepted in, I think, 2.4.12.  The code reappeared in 2.4.18 and
      sometime in the 2.5 tree before 2.5.15, breaking applications that use
      thread groups.
      
      As part of chasing this down, I figured out a way to remove the race
      condition while still preserving this behavior.  I've attached a patch
      against 2.5.15 that fixes it.

      [PATCH] fix scsi oops on failed sg table allocation · 7dbe32be
      Jens Axboe authored
      This patch fixes the deliberate BUG_ON() on failed sgtable allocations.
      I left that in because I was too lazy to fix it at the time...
      
      Basically make scsi_init_io() return 0 on failure (like before) but this
      time allow us to recover. scsi_init_io() will end_request on a fatal
      condition. So now just mark the device/host as starved if needed, and
      leave the request at the front of the queue for next service.

      [PATCH] Micro Memory battery backed RAM card driver · 76e7b902
      Neil Brown authored
      New driver for Micro Memory NVRAM module
      
      This driver handles up to 16 PCI based NVRAM cards
      from MicroMemory.
      Each card appears like a block device, and can be partitioned
      using any standard partitioning tool.  Upto 15 partitions are
      supported.
      
      This driver needs its own major device number and so allocates
      one using register_blkdev.

      [PATCH] 2.5.15 IDE 63 · d7e09f7e
      Martin Dalecki authored
      - Propagate the queue handling changes to pmac as well.
      
      - Move set_transfer to ide-taskfile.c this is the only place where it's used
         and it can be made static there. Same applies to ide_ata66_check().
      
      - Move ide_auto_reduce_xfer to ide.c.
      
      - Make ide_cmd() local to the only place where it's used. Rename it to
         drive_cmd(). Don't pass drive_cmd_intr() as parameter.
      
      - Remove ide_next command completion type. Nobody is using it.
      
      - Move ide_do_drive_cmd to ide-taskfile. It's used there and in sub-drivers.
         Not in ide.c. The usage inside the device type drivers is entirely bogus
         inconsistent and so on...
      
      - Kill bogus IRQ masking code. The kernel is supposed to handle this properly.
         We should not try to work against possible bugs in the overall irq handling
         code. Wow this is increasing the systems overall responsibility by a
         significant margin.
      
      - Remove disfunctional pdcadma code. It is only misleading to the user.

      [PATCH] 2.5.15 IDE 62a · 5ff49f70
      Martin Dalecki authored
      - Streamline device detection reporting to always use ->slot_name.
      
      - Apply 64 bit sector size fixes to the overall code.
      
      - Push ->handler down to the struct ata_channel.
      
      - Introduce channel group based locking instead of a single global lock for all
         operations. There are still some places where we have preserved the ide_lock.
         We can't lock for queues during device probe and we protect global data
         structures during device registration and unregistration in ide.c with it.
      
      - Start replacement of serialized access to the registers of
         channels which share them with proper host chip driver specific locking.
         This affects the following host chip drivers:
      
         cmd640.c, rz1000, ... ?
      
         Seems some are setting the serialize flag just in case. So better let's do it
         gradually over time.
      
         Well, I still have to think whatever we really need to put channels sharing
         an IRQ line in the same locking group.
      
         From now on the sick concept of a hw group is gone now. We have full blown
         per channel request queues! Hopefully I will be able soon to get my hands on
         a dual Athlon machine to check how this all behaves on a multi SMP machine.
      
      - Move the whole SUPPORT_VLB_SYNC stuff to the only place where it is used: the
         pdc4030 host chip driver.  Eliminate it from the global driver part.
      
      - Eliminate pseudo portability macros from pdc4030. This is a host chip firmly
         based on VLB.

      - Fix locking order in ioctl.
      
      - Fix wrong time_after usage introduced in 60. Maybe the fact I always get is
         wrong is related to the fact that I'm using the mouse with the left hand!?
      
      - Apply arch-clean-2 by Bartlomiej Zolnierkiewicz.
      
      - Don't disable interrupts during ide_wait_stat(). I see no reason too.
      
      - Push flags down from hwgroup to the ata_chaannel structure.
      
      - Apply small fixes from Franz Sirl to make AEC6280 working properly again.

      This patch further cleans up and separates the code in an effort to
      allow setting (a) a larger maximum real-time priority than default and

      [PATCH] USB-UHCI-HCD · a96a4b53
      Georg Acher authored
      After maturing for more than a month, I decided that it's enough...
      So here's the patch for the HCD-version of usb-uhci, I called it
      usb-uhci-hcd. For me, the usual devices work (TM).
      
      Since the internals haven't changed much, I don't expect much difference to
      usb-uhci in functionality and performance.
      
      There is one major improvement: I've added a (preliminary) watchdog, that
      regularly checks whether UHCI interrupts are coming through. If they are
      "missing", ie. the HC halted without saying so, the HC is "re-animated" by a
      real and clean restart, which is (internally) equivalent to a module-reload.
      This is especially for VIA-chips which get comatose quite easily by babble
      or other incorrect transfers.
      
      The side effect is, of course, disconnects for all connected devices, but
      they re-appear after a few seconds and were dead before anyway. So keyboard
      and mouse work again, which is IMO a _very_ useful thing :-)
      
      Another point: The watchdog (currently with moderate 8 interrupts/s) detects
      IRQ-problems, so the misleading "device doesn't accept new device"-message
      is replaced by an immediate error.
      
      More comments and the separation into multiple files (I've taken ohci-hcd as
      an example) should make the code more concise...
      
      A few things are still on the todo-list and will come later:
      - A few watchdog modifications (fewer interrupts, better diagnostics)
      - Support for module "tune"-parameters for breadth/depth search, debug etc.
      - interval support for ISO
      - More SMP-tests
      - maybe changes for reference counting when it is clear what survives :-)
