      [PATCH] Fix concurrent writepage and readpage · d58e41ee
      Andrew Morton authored
      Pages under writeback are not locked.  So it is possible (and quite
      legal) for a page to be under readpage() while it is still under
      writeback.  For a partially uptodate page with blocksize <
      PAGE_CACHE_SIZE.
      
      When this happens, the read and write I/O completion handlers get
      confused over the shared BH_Async usage and the page ends up not
      getting PG_writeback cleared.  Truncate gets stuck in D state.
      
      The patch separates the read and write I/O completion state.
      
      It also shuffles the buffer fields around.  Putting the
      commonly-accessed b_state at offset zero shrinks the kernel by a few
      hundred bytes because it can be accessed with indirect addressing, not
      indirect+indexed.

      [PATCH] Fix PG_launder · 4bcb6689
      Andrew Morton authored
      Set PG_launder against pages which are under VM writeback.  So page
      allocators will throttle against them.

      [PATCH] handle concurrent block_write_full_page and set_page_dirty · 46c709c0
      Andrew Morton authored
      set_page_dirty() runs without the page lock.  So
      __block_write_full_page() needs to be able to cope with the page's
      buffers being dirtied concurrently, on another CPU.
      
      Do this with careful ordering and a test-and-set.

      [PATCH] Fix SMP race in truncate · d028eab5
      Andrew Morton authored
      Closes a small race window: testing PageWriteback() outside the page
      lock introduces the possibility that page could be redirtied and have
      writeback started after we've inspected PageWriteback.

      [PATCH] Allow ext3 pages to be written back by VM pressure · 49c7cfe7
      Andrew Morton authored
      When ext3 refiles journalled buffers for writeback, it is better to set the
      page dirty as well as the buffer.  So the page will be written out by
      VM pressure rather than by kjournald alone.

      [PATCH] decouple swapper_space treatment from other address_spaces · 21bd2dfd
      Andrew Morton authored
      swapper_space is different.  Its pages are locked during writeout, it
      uses PAGE_SIZE rather than PAGE_CACHE_SIZE.  Converting swap to look
      more like the other address_spaces is a separate project.  This patch
      fully restores the old swap behaviour.
      
      - Don't dirty swapcache page buffers in set_page_dirty().
      
        Fixes a problem where __free_pte() runs set_page_dirty() and then
        immediately runs ClearPageDirty().  The pages ends up clean, with
        dirty buffers, and is unfreeable.
      
      - Hence, don't mark the page clean if its buffers are clean - swap
        does not have page/buffers dirty state coherency.

      [PATCH] Allow truncate to discard unmapped buffers · 6c8dd336
      Andrew Morton authored
      The buffer state "uptodate, dirty, unmapped" is legal.  It occurs when
      a mapped page with attached buffers which is over a hole is dirtied.
      
      So discard_buffer() needs to be able to discard those buffers as well;
      otherwise the page ends up clean, with dirty buffers and is unfreeable.

      [PATCH] radix-tree locking fix · 22eca178

      [PATCH] suppress allocation warnings for radix-tree allocations · 038de6b6
      Andrew Morton authored
      The recently-added page allocation failure warning generates a lot of
      noise due to radix-tree node allocation failures.  Those messages are
      not interesting.
      
      But I think the warning is otherwise useful - "I got an allocation
      failure and then it crashed" is better than "it crashed".
      
      The patch suppresses the message for ratnode allocation failures.

      [PATCH] [PATCH 2.5.13 IDE 54 · 5e229c99
      Martin Dalecki authored
       - Finish the changes from patch 53. ide_dma_actaion_t is gone now as well as
         whole hidden code paths associated with it. I hope I didn't mess too many
         things up with this, since the sheer size of the changes make them sensitive.
         (Tested on tree different host chip sets so it shouldn't be too bad...)
      
         Just still some minor cleanup remaining to be done in this area. The tags
         lefts there are intentional.
      
         In esp. the ide_dma_on method in cy82c693 looks suspicious.
      
         Using udma_enable in ide-cd.c, ide-floppy.c and ide-tape.c is suspicious as
         well. We have just uncovered it.
      
         In the next round we will concentrate on the fixes people did send me
         last time.

      [PATCH] 2.5.13 IDE 53 · 3ddddcf2
      Martin Dalecki authored
       - Start splitting the functions for host chip handling in to separate entities.
         This change is quite sensitive and may cause some trouble but it's for
         certain worth it anyway, because it should for example provide a much better
         infrastructure for th handling of different architectures.

      [PATCH] 2.5.13 IDE 52 · ab08629c
      Martin Dalecki authored
      Adapted from patch Bar³omiej ¯o³nierkiewicz:
      
       - make straight8 a flag in ata_channel instead of byte
      
       - don't store tables as code in drive_is_flashcard()
         and ide_xfer_verbose()
      
       - fix init_gendisk() (due to 2.5.13 blksize_size[] change)
      
       - compress region requesting/releasing
         in channel_probe() and ide_unregister()
      
       - clean a bit ide_setup_ports()
      
      Start of DMA handling tratment.
      
       - Fix the parameters to ide_build_dmatable() to be channel and request.
         Rename it to udma_new_table(). udma will mark arch specific functions
         later.
      
       - Let ide_start_dma() take the request directly as an arguemnt. Rename it to
         ata_start_dma(). After realizing that the usage of the func argument of it
         was bogous and that nobody is using rwproc we where able to remove both of
         them.
      
       - Fix ide_destroy_dmatable() to take the channel as argument and rename it to
         udma_destroy_table(). This function should have possible architecture
         specific implementation as well at some point in time.
      
       - Split up the TCQ UDMA handling stuff in to proper functions. Jens must has
         been dreaming as he introduced them ;-).

      NTFS: Release 2.0.6 - Major bugfix to make compatible with other kernel changes. · 70d3a085
      Anton Altaparmakov authored
      - Initialize the mftbmp address space properly now that there are more
      fields in the struct address_space. This was leading to hangs and
      oopses on umount since 2.5.12 because of changes to other parts of
      the kernel. We probably want a kernel generic init_address_space()
      function...
      - Drop BKL from ntfs_readdir() after consultation with Al Viro. The
      only caller of ->readdir() is vfs_readdir() which holds i_sem during
      the call, and i_sem is sufficient protection against changes in the
      directory inode (including ->i_size).
      - Use generic_file_llseek() for directories (as opposed to
      default_llseek()) as this downs i_sem instead of the BKL which is
      what we now need for exclusion against ->f_pos changes considering we
      no longer take the BKL in ntfs_readdir().

      [PATCH] IDE PIO mode Fix · 359e8441
      Osamu Tomita authored
      I found this bug in 2.5.10 first. And caused ext2 FS corruption.
      We are porting Linux to PC-9801 architecture (made by NEC Japan).
      It has PIO ONLY IDE I/F. So please check PIO mode too.
      
      It was introduced in 2.5.9 and still exists in 2.5.13, and caused
      superblock corruption for Andries.  This fixes it.

      Andries E. Brouwer authored
      Andrej Lajovic observes that in kd.h the definitions of K_NUMLOCK and
      K_CAPSLOCK are interchanged.  He is right (and this is the case since
      1.1.54; nobody noticed because setleds.c does not use these defines).
      So, here is the fix.  No kernel behaviour is changed.

      Trond Myklebust authored
      xprt.c:
        Speed up synchronous RPC over TCP calls by having the
        replies delivered by the IPV4 "bottom half", instead of
        switching to the rpciod process in order to call recvmsg().
         - Remove sock_recvmsg() interface.
         - Remove rpc_xprt_pending list and rpciod_tcp_dispatcher() interface.
         - Use the new tcp_read_sock() interface to deliver data directly
           from within tcp_data_ready().
      sched.c:
         - Remove references to rpciod_tcp_dispatcher.

         - New set of flags to reflect the TCP record read state.
