Hi there!

Bug Report Filed: https://bugzilla.kernel.org/show_bug.cgi?id=70091
Linux Version [3.13]
Configuration: Default configuration for x86

In function (swap_inode_boot_loader) in file (linux-3.13/fs/ext4/ioctl.c):

The structures: (inode->i_mutex) and (inode_bl->i_mutex) gets
successfully locked at line (133) by (lock_two_nondirectories(inode,
inode_bl), but both are not unlocked when the function returns after
line (147), however they got unlocked only at line (208) by
(unlock_two_nondirectories(inode, inode_bl)).

A possible solution is to call (unlock_two_nondirectories(inode,
inode_bl)) before line (147).

Thanks,
Ahmed
