      [PATCH] inotify · 0eeca283
      Robert Love authored
      
      
      inotify is intended to correct the deficiencies of dnotify, particularly
      its inability to scale and its terrible user interface:
      
              * dnotify requires the opening of one fd per each directory
                that you intend to watch. This quickly results in too many
                open files and pins removable media, preventing unmount.
              * dnotify is directory-based. You only learn about changes to
                directories. Sure, a change to a file in a directory affects
                the directory, but you are then forced to keep a cache of
                stat structures.
              * dnotify's interface to user-space is awful.  Signals?
      
      inotify provides a more usable, simple, powerful solution to file change
      notification:
      
              * inotify's interface is a system call that returns a fd, not SIGIO.
      	  You get a single fd, which is select()-able.
              * inotify has an event that says "the filesystem that the item
                you were watching is on was unmounted."
              * inotify can watch directories or files.
      
      Inotify is currently used by Beagle (a desktop search infrastructure),
      Gamin (a FAM replacement), and other projects.

      [PATCH] isofs: show hidden files, add granularity for assoc/hidden files flags · 9769f4eb
      Jeremy White authored
      The current isofs treatment of hidden files is flawed in two ways.  First,
      it does not provide sufficient granularity; it hides both 'hidden' files
      and 'associated' files (resource fork for Mac files).  Second, the default
      behavior to completely strip hidden files, while an admirable
      implementation of the spec, is a poor choice given the real world use of
      hidden files as a poor mans copy protection scheme for MSDOS and Windows
      based systems.  A longer description of this is available here:
      
         http://www.uwsg.iu.edu/hypermail/linux/kernel/0205.3/0267.html
      
      
      
      This patch was originally built after a few private conversations with Alan
      Cox; I shamefully failed to persist in seeing it go forward, I hope to make
      amends now.
      
      This patch introduces granularity by allowing explicit control for both
      hidden and associated files.  It also reverses the default so that by
      default, hidden files are treated as regular files on the iso9660 file
      system.
      
      This allow Wine to process Windows CDs, including those that are hybrid
      Mac/Windows CDs properly and completely, without our having to go muck up
      peoples fstabs as we do now.  (I have tested this with such a hybrid +
      hidden CD and have verified that this patch works as claimed).

      [PATCH] shmem: restore superblock info · 0edd73b3
      Hugh Dickins authored
      
      
      To improve shmem scalability, we allowed tmpfs instances which don't need
      their blocks or inodes limited not to count them, and not to allocate any
      sbinfo.  Which was okay when the only use for the sbinfo was accounting
      blocks and inodes; but since then a couple of unrelated projects extending
      tmpfs want to store other data in the sbinfo.  Whether either extension
      reaches mainline is beside the point: I'm guilty of a bad design decision,
      and should restore sbinfo to make any such future extensions easier.
      
      So, once again allocate a shmem_sb_info for every shmem/tmpfs instance, and
      now let max_blocks 0 indicate unlimited blocks, and max_inodes 0 unlimited
      inodes.  Brent Casavant verified (many months ago) that this does not
      perceptibly impact the scalability (since the unlimited sbinfo cacheline is
      repeatedly accessed but only once dirtied).
      
      And merge shmem_set_size into its sole caller shmem_remount_fs.

      [PATCH] Driver Core: remove driver model detach_state · 0b405a0f
      David Brownell authored
      
      
      The driver model has a "detach_state" mechanism that:
      
       - Has never been used by any in-kernel drive;
       - Is superfluous, since driver remove() methods can do the same thing;
       - Became buggy when the suspend() parameter changed semantics and type;
       - Could self-deadlock when called from certain suspend contexts;
       - Is effectively wasted documentation, object code, and headspace.
      
      This removes that "detach_state" mechanism; net code shrink, as well
      as a per-device saving in the driver model and sysfs.

      Linux-2.6.12-rc2 · 1da177e4
      Linus Torvalds authored
      Initial git repository build. I'm not bothering with the full history,
      even though we have it. We can create a separate "historical" git
      archive of that later if we want to, and in the meantime it's about
      3.2GB when imported into git - space that would just make the early
      git days unnecessarily complicated, when we don't have a lot of good
      infrastructure for it.
      
      Let it rip!
