Revision 68ac8bfb6aa4ce1a146b5a291f03fc2dd6d17cf2 authored by Jeff Mahoney on 27 February 2013, 19:43:09 UTC, committed by Jan Kara on 11 March 2013, 21:05:56 UTC
The bulk of __dquot_initialize runs under the dqptr_sem which protects the inode->i_dquot pointers. It doesn't protect the dereferenced contents, though. Those are protected by the dq_data_lock, which is missing around the dquot_resv_space call. Signed-off-by: Jeff Mahoney <jeffm@suse.com> Signed-off-by: Jan Kara <jack@suse.cz>
