From: Peter Zijlstra Date: Tue, 16 Oct 2007 04:47:54 +0000 (+0200) Subject: lockdep: fixup the inode dir annotation X-Git-Tag: v2.6.24-rc1~840 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=1e89a5e15a2c88b3fd1ed3fa17fd767efe44727a;p=platform%2Fupstream%2Fkernel-adaptation-pc.git lockdep: fixup the inode dir annotation A slight oversight tripped lockdep debugging code, each lockdep class should have but a single init site. Rearange the code to make this true.
