The patch titled
mmput() might sleep
has been added to the -mm tree. Its filename is
mmput-might-sleep.patch
See http://www.zip.com.au/~akpm/linux/patches/stuff/added-to-mm.txt to find
out what to do about this
From: Andrew Morton <akpm@xxxxxxxx>
exit_aio() and exit_mmap() can sleep. But it's easy to accidentally call
mmput() from inside locks.
