• af61b96b4   vfs: Abstract rcu_dereference_check for files-fdtable use ... Browse Code »

  Create an rcu_dereference_check_fdtable() that encapsulates the
  rcu_dereference_check() condition for fcheck_files() use. This
  has the beneficial side-effect of getting rid of a very long
  line.

• 21e544592   kmemtrace, fs: fix linux/fdtable.h header file dependencies ... Browse Code »

  Impact: cleanup

  We want to remove percpu.h from rcupdate.h (for upcoming kmemtrace
  changes), but this is not possible currently without breaking the
  build because fdtable.h has an implicit include file dependency: it
  uses __init does not include init.h.

  This can cause build failures on non-x86 architectures:

  /home/mingo/tip/include/linux/fdtable.h:66: error: expected '=', ',',
  ';', 'asm' or '__attribute__' before 'files_defer_init'
  make[2]: *** [fs/locks.o] Error 1

  We got this header included indirectly via rcupdate.h's percpu.h
  inclusion - but if that is not there the build will break.

  Fix it.

• b6b3fdead   filp_cachep can be static in fs/file_table.c ... Browse Code »

  Instead of creating the "filp" kmem_cache in vfs_caches_init(),
  we can do it a litle be later in files_init(), so that filp_cachep
  is static to fs/file_table.c
