staging: ion: always initialize the free list parameters

2015-01-18T00:16:00+00:00

Currently we initialize the heap free_lock and free list size in
ion_heap_init_deferred_free, which is only called when the
ION_HEAP_FLAG_DEFER_FREE heap flag is given.  However, the lock and size
are used in the shrinker path as well as the deferred free path, and we
can register a shrinker *without* enabling deferred freeing.  So, if a
heap provides a shrinker but *doesn't* set the DEFER_FREE flag we will
use these parameters uninitialized (resulting in a spinlock bug and
broken shrinker accounting).

Fix these problems by initializing the free list parameters directly in
ion_device_add_heap, which is always called no matter which heap
features are being used.

staging: android: ion: Deletion of unnecessary checks before two function calls

2014-11-26T21:42:53+00:00

The functions ion_heap_destroy() and vfree() perform also input
parameter validation. Thus the test around the call is not needed.

This issue was detected by using the Coccinelle software.

staging: android: Assign bool to true

2014-10-23T04:38:32+00:00

high is a bool type variable.

bool variable should be assigned true, false not 1 or 0.

This patch assigns high to true, replacing 1.

staging: android: ion: Replace "the the " with "the"

2014-10-20T02:29:17+00:00

This patch replace "the the " with "the".
The replacement couldn't be automated because sometimes
the first "the" was meant to be another word.

Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs

2014-10-13T09:28:42+00:00

Pull vfs updates from Al Viro:
 "The big thing in this pile is Eric's unmount-on-rmdir series; we
  finally have everything we need for that.  The final piece of prereqs
  is delayed mntput() - now filesystem shutdown always happens on
  shallow stack.

  Other than that, we have several new primitives for iov_iter (Matt
  Wilcox, culled from his XIP-related series) pushing the conversion to
  ->read_iter()/ ->write_iter() a bit more, a bunch of fs/dcache.c
  cleanups and fixes (including the external name refcounting, which
  gives consistent behaviour of d_move() wrt procfs symlinks for long
  and short names alike) and assorted cleanups and fixes all over the
  place.

  This is just the first pile; there's a lot of stuff from various
  people that ought to go in this window.  Starting with
  unionmount/overlayfs mess...  ;-/"
