[PATCH 0/2] fs,mm: abstract i_mmap_mutex lock

From: Davidlohr Bueso
Date: Wed Oct 02 2013 - 16:18:07 EST


In lure of the sleepable-vs-non-sleepable anon-vma/i_mmap locking
discussion, this patchset encapsulates the i_mmap_mutex lock into
two functions to lock and unlock (for writting). This is very similar
to how we currently deal with anon-vma lock, making it a lot easier to
change the lock type.

I've split these changes in to two patches since it makes patch 2 nicer
to review, matching additions with deletions.

Thanks!

mm,fs: introduce helpers around i_mmap_mutex
fs,mm: use new helper functions around the i_mmap_mutex
