Subject: [PATCH 0/5 -tip] umount_begin BKL pushdown
Date: Thu, 23 Apr 2009 21:12:00 +0200 [thread overview]
Message-ID: <1240513925-5603-1-git-send-email-abogani@texware.it> (raw)
Push the BKL acquisition from vfs to every specific filesystems
with hope that it can be eliminated in a second moment.
The first 4 patches add BKL lock into umount_begin() functions (for
the filesystems that have this handler). The last one remove
lock_kernel()/unlock_kernel() from fs/namespace.c (the only point
that invoke umount_begin() funtcions).
