From fd2dd9fbaf9e498ec63eef298921e36556f7214c Mon Sep 17 00:00:00 2001 From: Curt Wohlgemuth Date: Sat, 3 Apr 2010 17:44:16 -0400 Subject: ext4: Fix buffer head leaks after calls to ext4_get_inode_loc() 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.
