      ocfs2: Add reflinked file's inode to inode hash eariler. · c7d260af
      由 Tao Ma 提交于 
      We used to add reflinked file's inode to inode hash when
we add it to the dest dir. But actually there is a race.
Consider the following sequence.
1. reflink happens and create the inode in orphan dir.
2. reflink thread is scheduled out because of some io.
3. recovery begins to work and calls ocfs2_recover_orphans.
   It calls ocfs2_iget and get a new inode and i_count = 1.
   It calls iput then and delete inode. the buffer's
   uptodate state is cleared.

This patch move insert_inode_hash to the create function so
that it can be found by step 3 and prevented from deleting
because i_count > 1.

This resolves the bug

      CacheFiles: Update IMA counters when using dentry_open · 3350b2ac
      由 Marc Dionne 提交于 
      When IMA is active, using dentry_open without updating the
IMA counters will result in free/open imbalance errors when
fput is eventually called.

      SLOW_WORK: Fix the CONFIG_MODULES=n case · fa1dae49
      由 David Howells 提交于 
      Commits 3d7a641e ("SLOW_WORK: Wait for outstanding work items belonging to a
module to clear") introduced some code to make sure that all of a module's
slow-work items were complete before that module was removed, and commit
3bde31a4 ("SLOW_WORK: Allow a requeueable work item to sleep till the thread is
needed") further extended that, breaking it in the process if CONFIG_MODULES=n:

    CC      kernel/slow-work.o
  kernel/slow-work.c: In function 'slow_work_execute':
  kernel/slow-work.c:313: error: 'slow_work_thread_processing' undeclared (first use in this function)
  kernel/slow-work.c:313: error: (Each undeclared identifier is reported only once
  kernel/slow-work.c:313: error: for each function it appears in.)
  kernel/slow-work.c: In function 'slow_work_wait_for_items':
  kernel/slow-work.c:950: error: 'slow_work_unreg_sync_lock' undeclared (first use in this function)
  kernel/slow-work.c:951: error: 'slow_work_unreg_wq' undeclared (first use in this function)
  kernel/slow-work.c:961: error: 'slow_work_unreg_work_item' undeclared (first use in this function)
  kernel/slow-work.c:974: error: 'slow_work_unreg_module' undeclared (first use in this function)
  kernel/slow-work.c:977: error: 'slow_work_thread_processing' undeclared (first use in this function)
  make[1]: *** [kernel/slow-work.o] Error 1

Fix this by:

 (1) Extracting the bits of slow_work_execute() that are contingent on
     CONFIG_MODULES, and the bits that should be, into inline functions and
     placing them into the #ifdef'd section that defines the relevant variables
     and adding stubs for moduleless kernels.  This allows the removal of some
     #ifdefs.

 (2) #ifdef'ing out the contents of slow_work_wait_for_items() in moduleless
     kernels.

The four functions related to handling module unloading synchronisation (and
their associated variables) could be offloaded into a separate .c file, but
each function is only used once and three of them are tiny, so doing so would
prevent them from being inlined.
