2012-09-18userns: Convert struct dquot dq_id to be a struct kqidEric W. Biederman1-9/+13
Change struct dquot dq_id to a struct kqid and remove the now unecessary dq_type. Make minimal changes to dquot, quota_tree, quota_v1, quota_v2, ext3, ext4, and ocfs2 to deal with the change in quota structures and signatures. The ocfs2 changes are larger than most because of the extensive tracing throughout the ocfs2 quota code that prints out dq_id. quota_tree.c:get_index is modified to take a struct kqid instead of a qid_t because all of it's callers pass in dquot->dq_id and it allows me to introduce only a single conversion. The rest of the changes are either just replacing dq_type with dq_id.type, adding conversions to deal with the change in type and occassionally adding qid_eq to allow quota id comparisons in a user namespace safe way.

2011-01-10quota: Use %pV and __attribute__((format (printf in __quota_error and fix falloutJoe Perches1-4/+5
Use %pV in __quota_error so a single printk can not be interleaved with other logging messages. Add __attribute__((format (printf, 3, 4))) so format and arguments can be verified by compiler. Make sure printk formats and arguments match. Block # needed a pointer dereference. Signed-off-by: Joe Perches <joe@perches.com> Signed-off-by: Jan Kara <jack@suse.cz>
2010-07-21quota: Change quota error message to print out disk and function nameJiaying Zhang1-43/+42
The current quota error message doesn't always print the disk name, so it is hard to identify the "bad" disk when quota error happens. This patch changes the standardized quota error message to print out disk name and function name. It also uses a combination of cpp macro and inline function to provide better type checking and to lower the text size of the message.

2010-05-21dquot: Detect partial write error to quota file in write_blk() and add printk_ratelimit for quota error messagesJiaying Zhang1-19/+27
This patch changes quota_tree.c:write_blk() to detect error caused by partial write to quota file and add a macro to limit control printed quota error messages so we won't fill up dmesg with a corrupted quota file.

2010-05-21quota: Make quota stat accounting lockless.Dmitry Monakhov1-2/+2
Quota stats is mostly writable data structure. Let's alloc percpu bucket for each value. NOTE: dqstats_read() function is racy against dqstats_{inc,dec} and may return inconsistent value. But this is ok since absolute accuracy is not required. Signed-off-by: Dmitry Monakhov <dmonakhov@openvz.org> Signed-off-by: Jan Kara <jack@suse.cz>

2009-03-26quota: Remove dqbuf_t and other cleanupsJan Kara1-55/+49
Remove bogus typedef which is just a definition of char *. Remove unnecessary type casts. Substitute freedqbuf() with kfree. Signed-off-by: Jan Kara <jack@suse.cz>
