Subject[GIT PULL] aio changes for 3.12
Hell Linus, Al and everyone,

First off, sorry for this pull request being late in the merge window. Al
had raised a couple of concerns about 2 items in the series below. I
addressed the first issue (the race introduced by Gu's use of mm_populate()),
but he has not provided any further details on how he wants to rework the
anon_inode.c changes (which were sent out months ago but have yet to be
commented on). The bulk of the changes have been sitting in the -next tree
for a few months, with all the issues raised being addressed. Please
consider this pull. Thanks,
