From adaf14bef627b08726d0f91aeff2594e21451010 Mon Sep 17 00:00:00 2001 From: Curt Wohlgemuth Date: Sun, 30 May 2010 22:49:41 -0400 Subject: [PATCH] ext4: Fix buffer head leaks after calls to ext4_get_inode_loc() commit fd2dd9fbaf9e498ec63eef298921e36556f7214c upstream (as of v2.6.34-rc6) Calls to ext4_get_inode_loc() returns with a reference to a buffer head in iloc->bh. The callers of this function in ext4_write_inode() when in no journal mode and in ext4_xattr_fiemap() don't release the buffer head after using it.
