      [PATCH] inotify/idr leak fix · 8d3b3591
      Andrew Morton 提交于
      Fix a bug which was reported and diagnosed by
      Stefan Jones <stefan.jones@churchillrandoms.co.uk>
      
      IDR trees include a cache of idr_layer objects.  There's no way to destroy
      this cache, so when we discard an overall idr tree we end up leaking some
      memory.
      
      Add and use idr_destroy() for this.  v9fs and infiniband also need to use
      idr_destroy() to avoid leaks.
      
      Or, we make the cache global, like radix_tree_preload().  Which is probably
      better.  Later.

      [PATCH] inotify · 0eeca283
      Robert Love 提交于
      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.
