Subject: btrfs-progs: don't double-close prg_fd
X-Git-Tag: upstream/4.16.1~3459^2~8
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=6bd3a02fa67369c8a53c1b457e72c7330cfef3af;p=platform%2Fupstream%2Fbtrfs-progs.git

btrfs-progs: don't double-close prg_fd

If scrub start discovers that scrub is already running,
we need to set prg_fd to -1 before goto out, or we'll
try to close it again in the error path.
