Subject: [PATCH] Btrfs: add missing extent state caching calls
Date: Tue, 26 Nov 2013 15:01:34 +0000 [thread overview]
Message-ID: <1385478094-11984-1-git-send-email-fdmanana@gmail.com> (raw)
When we didn't find a matching extent state, we inserted a new one
but didn't cache it in the **cached_state parameter, which makes a
subsequent call do a tree lookup to get it.
