Subject: fuse2fs: fix error bailout in op_create
X-Git-Url: https://git.whamcloud.com/?a=commitdiff_plain;h=9f6d1bf3bbf16cef4a08b67894c827059dd401a8;p=tools%2Fe2fsprogs.git

fuse2fs: fix error bailout in op_create

Tim Woodall pointed out that op_create returns garbage error codes if
the ext2fs_extent_open2 in op_create fails.  Worse than that, it also
neglects to drop the bfl and leaks temp_path.  Let's fix all that.
