[PATCH] remove sb->s_files and file_list_lock usage in dquot.c
Iterate over sb->s_inodes instead of sb->s_files in add_dquot_ref. This reduces list search and lock hold time aswell as getting rid of one of the few uses of file_list_lock which Ingo identified as a scalability problem. Previously we called dq_op->initialize for every inode handing of a writeable file that wasn't initialized before. Now we're calling it for every inode that has a non-zero i_writecount, aka a writeable file descriptor refering to it. Thanks a lot to Jan Kara for running this patch through his quota test harness.
