      [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:

      PCI driver mgmt: · 52d16b41
      Patrick Mochel authored
      - Make sure proper pci id is passed to probe()

      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.

        Here's that patch again (MIME this time, so tabs don't get

        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

      [PATCH] correct zone_table comment · 5e04fa0a
      William Lee Irwin III authored
        The comment describing the usage of zone_table[] assumes the existence
        of an unsigned char page->zone field from the original implementation
        of page->zone size reduction. This patch corrects the comment to
        accurately describe the lookup mechanism used by page_zone() and also
        to mention explicitly the sole user of the table, page_zone().

      [PATCH] sys_sysinfo cleanup · 916e75e3
      Robert Love authored
      Looks like sys_sysinfo has not been touched in years.  Among other
      things, it uses a global cli() for protection; I switched it to an
      existing rwlock.  I also pulled it out of info.c and stuck it in timer.c
      (I choose timer.c because it shares dependencies there already).
      
      The details:
      
              - move sys_sysinfo to kernel/timer.c from kernel/info.c:
                why one small syscall got its own file is beyond me.
      
              - delete kernel/info.c
      
              - stop the global cli!  now grab a read_lock on xtime_lock.
                this is safe as we moved the write_unlock on xtime_lock
                down one line to cover the calculating of avenrun.

      Resend of trivial bits from my scheduler tree...:
      
              - shift cpu by 1UL not 1 to match type
              - clarify various comments
              - remove the barrier from preempt_schedule.  This was here
                because I used to check need_resched before returning from
                preempt_schedule but we do not now (although should).  The
                barrier insured need_resched and preempt_count were in sync

      [PATCH] capability.c cleanup · 810ccd09
      Robert Love authored
      I started looking into a couple FIXMEs in kernel/capability.c and I
      ended up with a fairly largish patch (although not quite so many changes
      to object code).
      
      First, it is unsafe to touch task->cap_* while not holding
      task_capability_lock.  The most notable occurrence of this is sys_access
      which saves the current cap_* values, changes them, does its business,
      then restores them.  In between all this they can change and then be
      restored to old values.  Unfortunately we cannot just grab the lock here
      since the function can sleep - I marked this with a FIXME for now.
      
      Second, I formalized the locking rules with task_capability_lock.  I
      declared the lock in include/linux/capability.h so other code can grab
      it.
      
      Finally, there is a whole boatload of code cleanup:
      
              - remove conditional locking/unlocking - that is just gross
              - don't pointlessly grab the read_lock twice
              - add/remove/edit comments
              - change some types (int -> pid_t, etc)
              - static inline two small functions that are called only
                once each
              - remove two FIXMEs
              - general code cleanup for readability and performance
      
      TODO:
      
              - fix sys_access and other cap_* accesses
              - do something about the annoying oddball 5-space indentation
                in kernel/capability.c !!
