staging/android: Add some more kerneldoc to ashmem.c

I am sorry if I have interpreted anything incorrectly here. This is my
second day really attempting to understand the Ashmem system.

I can not finish documenting this class at this stage - There is still
more that I have to learn. For now, however, it will have to do.

This introduces helper functions to make sure everything follows the

fact that some of the hotpaths don't even want to look at the LRU list

both the LRU list and for our temporary shrinking lists when removing
things from the LRU.

The helper functions temporarily have some extra sanity checking for the
flag bits that have to match the current LRU state of the dentry.  We'll
remove that before the final 3.12 release, but considering how easy it

Sachin Prabhu [Fri, 13 Sep 2013 13:11:57 +0000 (14:11 +0100)]
cifs: Avoid calling unlock_page() twice in cifs_readpage() when using fscache

When reading a single page with cifs_readpage(), we make a call to
fscache_read_or_alloc_page() which once done, asynchronously calls
the completion function cifs_readpage_from_fscache_complete(). This
completion function unlocks the page once it has been populated from
cache. The module then attempts to unlock the page a second time in
cifs_readpage() which leads to warning messages.

In case of a successful call to fscache_read_or_alloc_page() we should skip
the second unlock_page() since this will be called by the
cifs_readpage_from_fscache_complete() once the page has been populated by
fscache.

With the modifications to cifs_readpage_worker(), we will need to re-grab the
page lock in cifs_write_begin().

The problem was first noticed when testing new fscache patches for cifs.
