* quota: Change quota error message to print out disk and function nameJiaying Zhang2010-07-211-7/+4
| | | | | | | | | | | | | | 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 Zhang2010-05-211-3/+3
| | | | | | | | | | | 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: Improve checking of quota file headerJan Kara2009-12-231-1/+4
| | | | | | | | When we are asked for vfsv0 quota format and the file is in vfsv1 format (or vice versa), refuse to use the quota file. Also return with error when we don't like the header of quota file. Signed-off-by: Jan Kara <jack@suse.cz>

* quota: Implement quota format with 64-bit space and inode limitsJan Kara2009-12-101-33/+132
| | | | | | | | | | | | | So far the maximum quota space limit was 4TB. Apparently this isn't enough for Lustre guys anymore. So implement new quota format which raises block limits to 2^64 bytes. Also store number of inodes and inode limits in 64-bit variables as 2^32 files isn't that insanely high anymore. The first version of the patch has been developed by Andrew Perepechko <Andrew.Perepechko@Sun.COM>. CC: Andrew.Perepechko@Sun.COM Signed-off-by: Jan Kara <jack@suse.cz>
