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 
quota: add missing use of dq_data_lock in __dquot_initialize
 
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.
