[patch 06/38] quota: turn quotas off when remounting read-only

[Greg KH]

2.6.24-stable review patch.  If anyone has any objections, please let us
know.

------------------
 

From: Jan Kara <jack@xxxxxxx>

patch 66191dc622f5ff0a541524c4e96fdacfacfda206 in mainline.

Turn off quotas before filesystem is remounted read only.  Otherwise quota
will try to write to read-only filesystem which does no good...  We could
also just refuse to remount ro when quota is enabled but turning quota off
is consistent with what we do on umount.
