ext4: fix error paths in swap_inode_boot_loader()
commit 30d29b11 upstream. In swap_inode_boot_loader() we forgot to release ->i_mutex and resume unlocked dio for inode and inode_bl if there is an error starting the journal handle. This commit fixes this issue. Reported-by:Ahmed Tamrawi <ahmedtamrawi@gmail.com> Cc: Andreas Dilger <adilger.kernel@dilger.ca> Cc: Dr. Tilmann Bubeck <t.bubeck@reinform.de> Signed-off-by:
