From b216cbfb52c08300c203abf06ea9519d15d10045 Mon Sep 17 00:00:00 2001 From: Miao Xie Date: Wed, 15 May 2013 07:48:21 +0000 Subject: [PATCH] Btrfs: don't invoke btrfs_invalidate_inodes() in the spin lock context btrfs_invalidate_inodes() may sleep, so we should not invoke it in the spin lock context. Fix it.
