Subject: [ 09/23] ext4: fix duplicated mnt_drop_write call in EXT4_IOC_MOVE_EXT

From: Greg KH <gregkh@...uxfoundation.org>

3.4-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Al Viro <viro@...IV.linux.org.uk>

commit 331ae4962b975246944ea039697a8f1cadce42bb upstream.

Caused, AFAICS, by mismerge in commit ff9cb1c4eead ("Merge branch
'for_linus' into for_linus_merged")
