            Bug ID: 70091
           Summary: mutex_unlock is missed in function
                    (swap_inode_boot_loader) in file
                    (linux-3.13/fs/ext4/ioctl.c)
           Product: File System
           Version: 2.5
    Kernel Version: 3.13
          Hardware: x86-64
                OS: Linux
              Tree: Mainline
            Status: NEW
          Severity: normal
          Priority: P1
         Component: ext4
          Assignee: fs_ext4@...nel-bugs.osdl.org
          Reporter: atamrawi@...tate.edu
        Regression: No

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).
