[git pull] vfs queue, part 1
From: Al Viro
Date: Fri May 21 2010 - 22:13:38 EST
Assorted VFS and filesystem patches; the most drastic part from the core
VFS POV is the change of superblock refcounting and associated changes
to "do something to all filesystems that..." kind of loops. S_BIAS is
gone, atomic_inc_not_zero(&sb->s_active) is used by grab_super() instead
of playing these games and as the result we are able to do a massive
simplification of the locking rules. Additionally, we avoid a lot of
PITA with traversals of superblocks' list by leaving superblock on s_list
until the very end and checking for empty s_instances while iterating
through all superblocks to skip the ones that would've been already removed
by the code currently in tree.
There's a lot of other stuff as well, of course, but it's less serious
surgery. There *is* other tricky stuff for that cycle, but I'd rather
send a separate pull request or two for that in a couple of days.
Please, pull from
