commit: 3e36a16375eee390a9d80f99499fe630efa08128 From: Wei Yongjun <[email protected]> Date: Sat, 2 Mar 2013 17:13:55 -0500 Subject: ext4: fix possible memory leak in ext4_remount()
'orig_data' is malloced in ext4_remount() and should be freed before leaving from the error handling cases, otherwise it will cause memory leak.
