From 897c6ff9568bcb102ffc6b465ebe1def0cba829d Mon Sep 17 00:00:00 2001 From: Arjan van de Ven Date: Mon, 3 Jul 2006 00:25:28 -0700 Subject: [PATCH] lockdep: annotate sb ->s_umount The s_umount rwsem needs to be classified as per-superblock since it's perfectly legit to keep multiple of those recursively in the VFS locking rules. Has no effect on non-lockdep kernels.
