    Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs · 83373f70
    Linus Torvalds 提交于
    Pull vfs fixes from Al Viro:
     "double iput() on failure exit in lustre, racy removal of spliced
      dentries from ->s_anon in __d_materialise_dentry() plus a bunch of
      assorted RCU pathwalk fixes"
    
    The RCU pathwalk fixes end up fixing a couple of cases where we
    incorrectly dropped out of RCU walking, due to incorrect initialization
    and testing of the sequence locks in some corner cases.  Since dropping
    out of RCU walk mode forces the slow locked accesses, those corner cases
    slowed down quite dramatically.
    
    * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs:
      be careful with nd->inode in path_init() and follow_dotdot_rcu()
      don't bugger nd->seq on set_root_rcu() from follow_dotdot_rcu()
      fix bogus read_seqretry() checks introduced in b37199e6
      move the call of __d_drop(anon) into __d_materialise_unique(dentry, anon)
      [fix] lustre: d_make_root() does iput() on dentry allocation failure
