      Attempt to better locking in device model core: · b1d0e423
      Patrick Mochel authored
      - remove device from driver's list on device_detach 
      - set device's driver to NULL
      - decrement reference count on driver on device_detach
      - remove devices from driver's list in driver_detach
      - use a write_lock instead of read_lock
      - don't lock around initialization of device fields
      
      - assume we have a bus in __remove_driver (we enforce this in driver_register)
      - do put_bus last in __remove_driver
      - lock bus around atomic_set in remove_driver and atomic_dec_and_test in put_driver
      - remove from bus's list while we have it locked

      [PATCH] Cleanup i386 <linux/init.h> abuses · 50da7d0e
      Tom Rini authored
      The following patch cleans up the i386 usage of <linux/init.h>.
      This remove <linux/init.h> from <asm-i386/system.h> which did not need
      it, <asm-i386/highmem.h> which only had it due to an extern using
      __init, which is not needed.
      
      This adds <linux/init.h> to <asm-i386/bugs.h> which actually has
      numerous __init functions and adds <linux/init.h> to 9 files inside of
      arch/i386 which were indirectly including <linux/init.h> previously.

      [PATCH] Allow mpage.c to build · ed913fe2
      Russell King authored
      When trying to build mpage.c for ARM, I get errors from bio.h since kdev_t
      isn't defined.  The following fixes this.
      
      (I fail to see how this can build for anyone as it currently stands; its
      probably something x86 specific buried in the asm-i386 includes.)

      Stephen Rothwell authored
      Another simple part of a Matthew Wilcox patch.
      
      We do not need to pass the file descriptor to the fcntl_[sg]etlk
      functions, only the struct file * which we have already got
      from the file descriptor and verified.

      [PATCH] 2.5.20 IDE 85 · 856dd13d
      Martin Dalecki authored
       - Work a bit on the automatic CRC error recovery handling. System still hangs.
         But one thing for sure - we don't have to use any specialized irq handler for
         it.
      
       - Since ioctl don't any longer submit requests to the queue without
         rq->special set, we can safely remove args_error handling from
         start_request.
      
       - Make REQ_SPECIAL usage in ide-floppy obvious.
      
       - Use REQ_SPECIAL everywhere instead of REQ_DRIVE_ACB. This is actually a bit
         dangerous but should work as far as I can see.
      
       - Unfold the now not REQ_SPECIAL specific dequeing part of ide_end_drive_cmd().
         Turns out that we can thereafter remove the calls to ide_end_drice_cmd() at
         places where the request type isn't REQ_SPECIAL all any longer. (tcq.c)
      
      
       - After the above operation it turns out that there are just two places where
         ide_end_drive_cmd remains, namely: ata_error, task_no_data_intr
         drive_cmd_intr.
      
         We can avoid it by changing the logics in ata_error a slightly.
      
         So now just to cases remain where ide_end_drive_cmd remains used:
         drive_cmd_intr and task_no_data_intr.
      
       - Now looking  a bit closer we can realize that drive_cmd_intr and
         task_no_data_intr can be easly merged together, since the usage of
         task_no_data_intr implied taskfile.sector_number == 0.
      
       - Use one single ata_special_intr function for the handling of interrupts
         submitted through ide_raw_cmd.
      
       - Move the remaining artefacts of ide_end_drive_cmd directly to
         ata_special_intr. Oh we don't need to check for REQ_SPECIAL any longer there,
         since the context is already known.
      
       - Set the ata_special_intr handler and command type directly inside
         ide_raw_taskfile to save code.

      [PATCH] remove fsuser() · 5fb4864a
      Robert Love authored
      This patch removes fsuser().  Now both suser() and fsuser() are gone and
      all permission checks use an appropriate capable() call.

      [PATCH] remove suser() · 95c78cd5
      Robert Love authored
      Attached patch replaces the lone remaining suser() call with capable()
      and then removes suser() itself in a triumphant celebration of the glory
      of capable().  Or something. ;-)
      
      Small cleanup of capable() and some comments, too.

      [PATCH] 2.5.20 IDE 84 · a73f75e2
      Martin Dalecki authored
       - Simplify ide_cmd_type_parse by removing the handling of commands which we
         never use.
      
       - Realize that pre_task_out_intr and pre_task_mulout_intr are semanticaly
         identical. Use only pre_task_out_intr(). This allowed us to
         eliminate the prehandler altogether.
      
       - Updated fix for misconfigured host chips by Vojtech Pavlik.
      
       - Be more permissive about ioctl handling to allow device type drivers to do
         they own checks.
      
       - ali14xx cleanups by Andrej Panin.
      
       - Unfold usage ide_cmd_type_parser in tcq.c code. This makes this operation
         local to ide-disk.c. Move it as well as the interrupt handlers used only for
         the handling of disk requests there too.
      
       - Guard against calling handler before the drive is ready for it in
         ata_taskfile()! Well this bug was there before, but right now we inform
         about it.
      
       - Unfold ide_cmd_type_praser in ide-disk.c. Merge the remaining bits of it with
         get_command. Well it's no more.
      
       - Move recal_intr to ide.c - the only place where it's used.
      
      This doesn't change the "mechanics" of the code but it makes it a lot more
      "obvious" what's going on.

      [PATCH] fix 2.5.20 ramdisk · 0f65c90d
      Russell King authored
      2.5.20 seems to be incapable of executing binaries in a ramdisk-based
      root filesystem.  The ramdisk in question is an ext2fs, with a 1K
      block size loaded via the compressed ramdisk loader in do_mounts().
      
      It appears that, in the case of a 1K block sized filesystem, we attempt
      to read two 512-byte sectors into a BIO vector.  The first one is copied
      into the first 512 bytes.  The second sector, however, is copied over
      the first 512 bytes.  Obviously not what we really want.
      
      Rev. 2, slightly cleaned up:

      Do manual traversing of drivers' devices list when unbinding the driver. · 96d36ec0
      Patrick Mochel authored
      driver_unbind was called when drv->refcount == 0.
      It would call driver_for_each_dev to do the unbinding
      The first thing that would do was get_device, which...
      BUG()'d if drv->refcount == 0. 
      Duh.

      device model udpate: · d6022129
      Patrick Mochel authored
      - make sure drv->devices is initialized on registration (from Peter Osterlund)
      - add remove_driver for forcing removal of driver
      
      There was a potential race with the module unload code. When a pci driver was unloaded, it would call pci_unregister_driver, which would simply call put_driver.
      If the driver's refcount wasn't 0, it wouldn't unbind it from devices, but the module unload would still continue. 
      If something tried to access the driver later (since everyone thinks its still there), Bad Things would happen. 
      This fixes it until there can be tighter integration between the device model and module unload code.

      Dan Kegel authored
        Here's that patch again (MIME this time, so tabs don't get
        lost by my silly gui mailer); applies cleanly against against 2.4.19-pre8.
        Nobody commented on it last time I posted it, and it does
        make compiling gcc easier, so I guess that makes it trivial patch
        monkey fodder.  Or am I making a silly mistake?

        Most /proc/slabinfo cache_names are in the format:
        cache_name.  There are a couple with spaces in the
        name, which is inconsistent and requires a special case
        when scripting.
      
        Changes "fasync cache" and "file lock cache" to have
        the usual underscore.
