Subject: ext4: fix error paths in swap_inode_boot_loader()
From: Zheng Liu <wenqing.lz@xxxxxxxxxx>
commit 30d29b119ef01776e0a301444ab24defe8d8bef3 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.
