* quota: Use %pV and __attribute__((format (printf in __quota_error and fix ↵Joe Perches2011-01-101-4/+5
| | | | | | | | | | | | | | | fallout 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.

* quota: Change quota error message to print out disk and function nameJiaying Zhang2010-07-211-43/+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.

* dquot: Detect partial write error to quota file in write_blk() and add ↵Jiaying Zhang2010-05-211-19/+27
| | | | | | | | | | | printk_ratelimit for quota error messages 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.

* quota: Make quota stat accounting lockless.Dmitry Monakhov2010-05-211-2/+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.
