2012-09-18userns: Convert struct dquot dq_id to be a struct kqidEric W. Biederman
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.

2010-07-21quota: Change quota error message to print out disk and function nameJiaying Zhang
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 ↵Jiaying Zhang
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.

2009-12-23quota: Improve checking of quota file headerJan Kara
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>

2009-12-10quota: Implement quota format with 64-bit space and inode limitsJan Kara
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>
