Subject: [PATCH] fsck: fix leak when traversing trees
Date: Sat, 20 Jan 2018 07:43:51 +0000 [thread overview]
Message-ID: <20180120074351.GA12439@whir> (raw)
While fsck_walk/fsck_walk_tree/parse_tree populates "struct tree"
idempotently, it is still up to the fsck_walk caller to call
free_tree_buffer.
Fixes: ad2db4030e42890e ("fsck: remove redundant parse_tree() invocation")
Signed-off-by: Eric Wong <e@80x24.org>

These APIs could probably be made to be less error-prone,
but at least this stops my little machine from OOM-ing.
