      [PATCH] go back to 256 requests per queue · 374cac7a
      Andrew Morton authored
      The request queue was increased from 256 slots to 512 in 2.5.20.  The
      throughput of `dbench 128' on Randy's 384 megabyte machine fell 40%.
      
      We do need to understand why that happened, and what we can learn from
      it.  But in the meanwhile I'd suggest that we go back to 256 slots so
      that this known problem doesn't impact people's evaluation and tuning
      of 2.5 performance.

      [PATCH] mark_buffer_dirty() speedup · 7a1a7f5b
      Andrew Morton authored
      mark_buffer_dirty() is showing up on Anton's graphs.  Avoiding the
      buslocked RMW if the buffer is already dirty should fix that up.

      [PATCH] grab_cache_page_nowait deadlock fix · 85bfa7dc
      Andrew Morton authored
      - If grab_cache_page_nowait() is to be called while holding a lock on
        a different page, it must perform memory allocations with GFP_NOFS.
        Otherwise it could come back onto the locked page (if it's dirty) and
        deadlock.
      
        Also tidy this function up a bit - the checks in there were overly
        paranoid.
      
      - In a few of places, look to see if we can avoid a buslocked cycle
        and dirtying of a cacheline.

      [PATCH] ext3 corruption fix · afb51f81
      Andrew Morton authored
      Stephen and Neil Brown recently worked this out.  It's a
      rare situation which only affects data=journal mode.
      
      Fix problem in data=journal mode where writeback could be left pending on a
      journaled, deleted disk block.  If that block then gets reallocated, we can
      end up with an alias in which the old data can be written back to disk over
      the new.  Thanks to Neil Brown for spotting this and coming up with the
      initial fix.

      [PATCH] writeback tunables · e3e529bf
      Andrew Morton authored
      Adds five sysctls for tuning the writeback behaviour:
      
      	dirty_async_ratio
      	dirty_background_ratio
      	dirty_sync_ratio
      	dirty_expire_centisecs
      	dirty_writeback_centisecs
      
      these are described in Documentation/filesystems/proc.txt  They are
      basically the tradiditional knobs which we've always had...
      
      We are accreting a ton of obsolete sysctl numbers under /proc/sys/vm/.
      I didn't recycle these - just mark them unused and remove the obsolete
      documentation.

      [PATCH] Net updates / CPU hotplug infrastructure missed merge · 88bccfb7
      Rusty Russell authored
      Ironically enough, both were written by me.
      
      Fixed thus.

      [PATCH] change_page_attr and AGP update · c8712aeb
      Andi Kleen authored
      Add change_page_attr to change page attributes for the kernel linear map.
      
      Fix AGP driver to use change_page_attr for the AGP buffer.
      
      Clean up AGP driver a bit (only tested on i386/VIA+AMD)
      
      Change ioremap_nocache to use change_page_attr to avoid mappings with
      conflicting caching attributes.

      [PATCH] export pci_bus_type to modules. · 68d6275b
      Stelian Pop authored
      This exports the pci_bus_type symbol to modules, needed by (at least)
      the recent changes in pcmcia/cardbus.c.

      [PATCH] scheduler whitespace/comment merge from -ac · 48fc1713
      Robert Love authored
      Attached patch brings over the sane bits from 2.4-ac: i.e. if Linus
      merges this and Alan merges your patch minus my complaints, the two
      trees will be in sync...

      [PATCH] 2.5.21 ide 92 · 78929a18
      Martin Dalecki authored
       - Finally unify task_in_intr and task_mulin_intr. One crucial code path less to
         watch out, but a quite dangerous step in itself. PIO reading is functional
         again. The next step will be the unification of the write path of course.
      
       - Introduce a small helper for the execution of task file commands which
         basically just send a simple command down to the drive.
      
       - Add a buffer parameter to ide_raw_taskfile allowing to unify the handling of
         ioctl and normal ide_raw_taskfile request.
      
       - Fix some small function pointer type mismatches.
      
      Apply more host chip controller clenups by Bartlomiej:
      
           - move setting drive->current_speed from *_tune_chipset()
             to ide_config_drive_speed()
      
          cmd64x.c:
      	- convert cmd64x_tuneproc() to use ata-timing library
      	- clean cmd64x_tune_chipset() and cmd680_tune_chipset()
      
          hpt366.c:
      	- remove empty timings table
      
          it8172.c:
      	- kill prototypes
      	- update to new udma_setup() scheme
      
          - misc cleanups

      cardbus.c: · 9f64c00f
      Linus Torvalds authored
        Set up CardBus cards correctly: initialize them fully
        before calling device_register(), and make sure to tell
        the world that it's a PCI-like bus.

      [PATCH] suspend-to-{ram/disk} cleanups/fixes for 2.5.21 · ef8e826c
      Pavel Machek authored
      This kills Sysrq-D support (did not work anyway, and complicated
      code).
      
      Adds resume support to i8259A (otherwise interrupts will not work
      after S3).
      
      HAVE_NEW_DEVICE_MODEL is always true in 2.5, so we should define
      it. S3 can't work properly without that. Also limit toshiba workaround
      to S1. (This hide lack of i8259A support for me).
      
      Fixes compilation, and kills <asm/suspend.h> being included
      twice with ugly hacks around.

      François Romieu authored
      - (leak) memory allocated in dscc4_found1() isn't freed by caller in error path.
        dscc4_free1() is now in charge of this duty.
      - (style) code factored in dscc4_remove_one after use of dscc4_free1().
