2009-01-05quota: Convert union in mem_dqinfo to a pointerJan Kara1-19/+34
Coming quota support for OCFS2 is going to need quite a bit of additional per-sb quota information. Moreover having fs.h include all the types needed for this structure would be a pain in the a**. So remove the union from mem_dqinfo and add a private pointer for filesystem's use. Signed-off-by: Jan Kara <jack@suse.cz> Signed-off-by: Mark Fasheh <mfasheh@suse.com>
2009-01-05quota: Split off quota tree handling into a separate fileJan Kara1-544/+52
There is going to be a new version of quota format having 64-bit quota limits and a new quota format for OCFS2. They are both going to use the same tree structure as VFSv0 quota format. So split out tree handling into a separate file and make size of leaf blocks, amount of space usable in each block (needed for checksumming) and structures contained in them configurable so that the code can be shared.

2009-01-05quota: Move quotaio_v[12].h from include/linux/ to fs/Jan Kara1-3/+4
Since these include files are used only by implementation of quota formats, there's no need to have them in include/linux/. Signed-off-by: Jan Kara <jack@suse.cz> Signed-off-by: Mark Fasheh <mfasheh@suse.com>
2009-01-05quota: Increase size of variables for limits and inode usageJan Kara1-4/+17
So far quota was fine with quota block limits and inode limits/numbers in a 32-bit type. Now with rapid increase in storage sizes there are coming requests to be able to handle quota limits above 4TB / more that 2^32 inodes. So bump up sizes of types in mem_dqblk structure to 64-bits to be able to handle this. Also update inode allocation / checking functions to use qsize_t and make global structure keep quota limits in bytes so that things are consistent.

2008-07-25quota: move function-macros from quota.h to quotaops.hJan Kara1-0/+1
Move declarations of some macros, which should be in fact functions to quotaops.h. This way they can be later converted to inline functions because we can now use declarations from quota.h. Also add necessary includes of quotaops.h to a few files.

2008-04-28quota: do not allow setting of quota limits to too high valuesAndrew Perepechko1-0/+3
We should check whether quota limits set via Q_SETQUOTA are not exceeding limits which quota format is able to handle.

2006-01-14[PATCH] quota: make useless quota error message informativeValdis.Kletnieks@vt.edu1-1/+2
fs/quota_v2.c can, under some conditions, issue a kernel message that says, in totality, 'failed read'. This patch does the following: 1) Gives a hint who issued the error message, so people reading the logs don't have to go grepping the entire kernel tree (with 11 false positives). 2) Say what amount of data we expected, and actually got.

2005-04-16[PATCH] quota: possible bug in quota format v2 supportNiu YaWei1-1/+2
Don't put root block of quota tree to the free list (when quota file is completely empty). That should not actually happen anyway (somebody should get accounted for the filesystem root and so quota file should never be empty) but better prevent it here than solve magical quota file corruption.

2005-04-16Linux-2.6.12-rc2v2.6.12-rc2Linus Torvalds1-0/+693
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
