X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=6e381418904027a9f968e97403add5bda03fb319;p=platform%2Fupstream%2Fbtrfs-progs.git

btrfs-progs: fix memory leak in btrfs-map-logical main()

In btrfs-map-logical main(), strdup() allocates memory to output_file,
but that memory is not freed.
So add missing free() calls before return.
