Date: Fri, 28 Dec 2007 15:42:50 -0500 From: Erez Zadok <ezk@...sunysb.edu> To: akpm@...ux-foundation.org Cc: linux-kernel@...r.kernel.org, linux-fsdevel@...r.kernel.org, viro@....linux.org.uk, hch@...radead.org, Erez Zadok <ezk@...sunysb.edu> Subject: [PATCH 16/30] Unionfs: remove unnecessary lock in read_inode Our read_inode doesn't need to grab the superblock rwsem because there no chance it could be affected by branch management. But our read_inode was called from other places which did grab need to grab that rwsem, and lockdep complained.
