      Linux 4.0-rc1 · c517d838
      Linus Torvalds 提交于
      .. after extensive statistical analysis of my G+ polling, I've come to
      the inescapable conclusion that internet polls are bad.
      
      Big surprise.
      
      But "Hurr durr I'ma sheep" trounced "I like online polls" by a 62-to-38%
      margin, in a poll that people weren't even supposed to participate in.
      Who can argue with solid numbers like that? 5,796 votes from people who
      can't even follow the most basic directions?
      
      In contrast, "v4.0" beat out "v3.20" by a slimmer margin of 56-to-44%,
      but with a total of 29,110 votes right now.
      
      Now, arguably, that vote spread is only about 3,200 votes, which is less
      than the almost six thousand votes that the "please ignore" poll got, so
      it could be considered noise.
      
      But hey, I asked, so I'll honor the votes.

      debugfs: leave freeing a symlink body until inode eviction · 0db59e59
      Al Viro 提交于
      As it is, we have debugfs_remove() racing with symlink traversals.
      Supply ->evict_inode() and do freeing there - inode will remain
      pinned until we are done with the symlink body.
      
      And rip the idiocy with checking if dentry is positive right after
      we'd verified debugfs_positive(), which is a stronger check...

      trylock_super(): replacement for grab_super_passive() · eb6ef3df
      Konstantin Khlebnikov 提交于
      I've noticed significant locking contention in memory reclaimer around
      sb_lock inside grab_super_passive(). Grab_super_passive() is called from
      two places: in icache/dcache shrinkers (function super_cache_scan) and
      from writeback (function __writeback_inodes_wb). Both are required for
      progress in memory allocator.
      
      Grab_super_passive() acquires sb_lock to increment sb->s_count and check
      sb->s_instances. It seems sb->s_umount locked for read is enough here:
      super-block deactivation always runs under sb->s_umount locked for write.
      Protecting super-block itself isn't a problem: in super_cache_scan() sb
      is protected by shrinker_rwsem: it cannot be freed if its slab shrinkers
      are still active. Inside writeback super-block comes from inode from bdi
      writeback list under wb->list_lock.
      
      This patch removes locking sb_lock and checks s_instances under s_umount:
      generic_shutdown_super() unlinks it under sb->s_umount locked for write.
      New variant is called trylock_super() and since it only locks semaphore,
      callers must call up_read(&sb->s_umount) instead of drop_super(sb) when
      they're done.

      Fanotify probably doesn't want to watch autodirs so make it use d_can_lookup()
      rather than d_is_dir() when checking a dir watch and give an error on fake
      directories.
