      [PATCH] autofs4 needs to force fail return revalidate · bcdc5e01
      Ian Kent 提交于
      For a long time now I have had a problem with not being able to return a
      lookup failure on an existsing directory.  In autofs this corresponds to a
      mount failure on a autofs managed mount entry that is browsable (and so the
      mount point directory exists).
      
      While this problem has been present for a long time I've avoided resolving
      it because it was not very visible.  But now that autofs v5 has "mount and
      expire on demand" of nested multiple mounts, such as is found when mounting
      an export list from a server, solving the problem cannot be avoided any
      longer.
      
      I've tried very hard to find a way to do this entirely within the autofs4
      module but have not been able to find a satisfactory way to achieve it.
      
      So, I need to propose a change to the VFS.

      [PATCH] autofs4: NFY_NONE wait race fix · a5370553
      Ian Kent 提交于
      This patch fixes two problems.
      
      First, the comparison of entries in the waitq.c was incorrect.
      
      Second, the NFY_NONE check was incorrect. The test of whether the dentry
      is mounted if ineffective, for example, if an expire fails then we could
      wait forever on a non existant expire. The bug was identified by Jeff
      Moyer.
      
      The patch changes autofs4 to wait on expires only as this is all that's
      needed.  If there is no existing wait when autofs4_wait is call with a type
      of NFY_NONE it delays until either a wait appears or the the expire flag is
      cleared.

      [PATCH] shrink dentry struct · 5160ee6f
      Eric Dumazet 提交于
      Some long time ago, dentry struct was carefully tuned so that on 32 bits
      UP, sizeof(struct dentry) was exactly 128, ie a power of 2, and a multiple
      of memory cache lines.
      
      Then RCU was added and dentry struct enlarged by two pointers, with nice
      results for SMP, but not so good on UP, because breaking the above tuning
      (128 + 8 = 136 bytes)
      
      This patch reverts this unwanted side effect, by using an union (d_u),
      where d_rcu and d_child are placed so that these two fields can share their
      memory needs.
      
      At the time d_free() is called (and d_rcu is really used), d_child is known
      to be empty and not touched by the dentry freeing.
      
      Lockless lookups only access d_name, d_parent, d_lock, d_op, d_flags (so
      the previous content of d_child is not needed if said dentry was unhashed
      but still accessed by a CPU because of RCU constraints)
      
      As dentry cache easily contains millions of entries, a size reduction is
      worth the extra complexity of the ugly C union.

      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!
