Subject: [RFC][PATCH 0/4] configfs: Make nested default groups lockdep-friendly v2
Date: Thu, 22 May 2008 13:40:48 +0200	[thread overview]
Message-ID: <20080522114048.265996107@kerlabs.com> (raw)

Hi all,

The following patchset is another try to make configfs recursive inode locking
lockdep-friendly. This time lockdep_off()/lockdep_on() are not inserted, but
I_MUTEX_* lockdep sub-classes are tweaked to allow some variable-length
recursion on the spirit of I_MUTEX_PARENT -> I_MUTEX_CHILD -> I_MUTEX_CHILD + 1
-> ... The lockdep annotations added in configfs are a variant of a previously
submitted patch (see
http://oss.oracle.com/pipermail/ocfs2-devel/2008-May/002214.html ), with a much
lighter footprint, thanks to a suggestion from Joel.

Thanks for reviewing.

Louis
