Subject: LU-687 ldiskfs: resolve section dynlocks mismatch
X-Git-Tag: 2.1.56~37
X-Git-Url: https://git.whamcloud.com/?p=fs%2Flustre-release.git;a=commitdiff_plain;h=182c2f8a6dd1a7d8493e5442656a5071333beb17

LU-687 ldiskfs: resolve section dynlocks mismatch

Fix __init/__exit section mismatch.

  WARNING: lustre-2.1.0/ldiskfs/ldiskfs/ldiskfs.o(.init.text+0x1bc):
  Section mismatch in reference from the function init_module() to the
  function .exit.text:dynlock_cache_exit().  An __init init_module()
  function references a function __exit dynlock_cache_exit().

  This is often seen when error handling in the init function uses
  functionality in the exit path.  The fix is often to remove the
  __exit annotation of dynlock_cache_exit() so it may be used outside
  an exit section.
