Re: btrfs defrag kernel 3.11
ive had the same problem and this commit helped, which i had to cherry-pick:
commit c83b3452db6e1b048312c50b23f06c9634535f80
Author: Josef Bacik
Date: Mon Jul 22 12:50:37 2013 -0400
Btrfs: reset ret in record_one_backref
I was getting warnings when running find ./ -type f -exec btrfs fi
defrag -f {}
\; from record_one_backref because ret was set. Turns out it was
because it was
set to 1 because the search slot didn't come out exact and we
never reset it.
So reset it to 0 right after the search so we don't leak this and get
uneccessary warnings. Thanks,
Ahmet
