Subject: Dirtiable inode bdi default != sb bdi btrfs
Date: Wed, 22 Sep 2010 21:54:30 -0300 [thread overview]
Message-ID: <4C9AA546.6050201@cesarb.net> (raw)
This started appearing for me on v2.6.36-rc5-49-gc79bd89; it did not
happen on v2.6.36-rc5-33-g1ce1e41, probably because it does not have
commit 692ebd17c2905313fff3c504c249c6a0faad16ec which introduces the
warning.

These are only the first two; they keep happening, with several
different processes (it is not only find), but always btrfs (I have /
and /home on btrfs and /boot on ext4). In case it makes any difference,
/dev seems to be on devtmpfs, and everything uses relatime.
There is also the following one which is not on vfs_readdir:
