https://git.stealer.net/cgit.cgi/user/sven/linux.git/atom?h=v3.82012-07-14T12:37:27ZVFS: Make clone_mnt()/copy_tree()/collect_mounts() return errors2012-07-14T12:37:27ZDavid Howellsdhowells@redhat.com2012-06-25T11:55:18Zurn:sha1:be34d1a3bc4b6f357a49acb55ae870c81337e4f0
copy_tree() can theoretically fail in a case other than ENOMEM, but always
returns NULL which is interpreted by callers as -ENOMEM. Change it to return
an explicit error.
Also change clone_mnt() for consistency and because union mounts will add new
error cases.
Thanks to Andreas Gruenbacher <agruen@suse.de> for a bug fix.

brlocks/lglocks: API cleanups2012-05-30T03:28:41ZAndi Kleenak@linux.intel.com2012-05-08T04:02:02Zurn:sha1:962830df366b66e71849040770ae6ba55a8b4aec
lglocks and brlocks are currently generated with some complicated macros
in lglock.h. But there's no reason to not just use common utility
functions and put all the data into a common data structure.
In preparation, this patch changes the API to look more like normal
function calls with pointers, not magic macros.
The patch is rather large because I move over all users in one go to keep
it bisectable. This impacts the VFS somewhat in terms of lines changed.
But no actual behaviour change.
