2010-03-05quota: clean up checks for supported quota methodsChristoph Hellwig1-84/+37

2010-03-05quota: Fix warning when a delayed write happens before quota is enabledJan Kara1-4/+31
If a delayed-allocation write happens before quota is enabled, the kernel spits out a warning: WARNING: at fs/quota/dquot.c:988 dquot_claim_space+0x77/0x112() because the fact that user has some delayed allocation is not recorded in quota structure. Make dquot_initialize() update amount of reserved space for user if it sees inode has some space reserved. Also make sure that reserved quota space does not go negative and we warn about the filesystem bug just once. Signed-off-by: Jan Kara <jack@suse.cz>
2010-03-05quota: manage reserved space when quota is not active [v2]Dmitry Monakhov2-6/+15
Since we implemented generic reserved space management interface, then it is possible to account reserved space even when quota is not active (similar to i_blocks/i_bytes). Without this patch following testcase result in massive comlain from WARN_ON in dquot_claim_space() TEST_CASE: mount /dev/sdb /mnt -oquota dd if=/dev/zero of=/mnt/test bs=1M count=1 quotaon /mnt # fs_reserved_spave == 1Mb # quota_reserved_space == 0, because quota was disabled dd if=/dev/zero of=/mnt/test seek=1 bs=1M count=1 # fs_reserved_spave == 2Mb # quota_reserved_space == 1Mb sync # ->dquot_claim_space() -> WARN_ON Signed-off-by: Dmitry Monakhov <dmonakhov@openvz.org> Signed-off-by: Jan Kara <jack@suse.cz>
2010-03-05jbd[2]: remove references to BUFFER_DEBUGChristoph Egger2-22/+0
CONFIG_BUFFER_DEBUG seems to have been removed from the documentation somewhere around 2.4.15 and seemingly hasn't been available even longer. It is, however, still referenced at one place from the jbd code (one is a copy of the other header).

2010-03-05ext3: trivial quota cleanupDmitry Monakhov1-54/+67
The patch is aimed to reorganize and simplify quota code a bit. Quota code is itself complex enouth, but we can make it more readable in some places: - Move quota option parsing to separate functions. - Simplify old-quota and journaled-quota mix check.

2010-03-05ext3: Use bitops to read/modify EXT3_I(inode)->i_stateJan Kara5-27/+44
At several places we modify EXT3_I(inode)->i_state without holding i_mutex (ext3_release_file, ext3_bmap, ext3_journalled_writepage, ext3_do_update_inode, ...). These modifications are racy and we can lose updates to i_state. So convert handling of i_state to use bitops which are atomic. Signed-off-by: Jan Kara <jack@suse.cz>
2010-03-05quota: Cleanup S_NOQUOTA handlingJan Kara1-36/+11
Cleanup handling of S_NOQUOTA inode flag and document it a bit. The flag does not have to be set under dqptr_sem. Only functions modifying inode's dquot pointers have to check the flag under dqptr_sem before going forward with the modification. This way we are sure that we cannot add new dquot pointers to the inode which is just becoming a quota file. The good thing about this cleanup is that there are no more places in quota code which enforce i_mutex vs. dqptr_sem lock ordering (in particular that dqptr_sem -> i_mutex of quota file). This should silence some (false) lockdep warnings with ext4 + quota and generally make life of some filesystems easier. Signed-off-by: Jan Kara <jack@suse.cz>

2010-03-01sata_via: Delay on vt6420 when starting ATAPI DMA writeBart Hartgers1-1/+16
When writing a disc on certain lite-on dvd-writers (also rebadged as optiarc/LG/...) connected to a vt6420, the ATAPI CDB ends up in the datastream and on the disc, causing silent corruption. Delaying between sending the CDB and starting DMA seems to prevent this. I do not know if there are burners that do not suffer from this, but the patch should be safe for those as well. There are many reports of this issue, but AFAICT no solution was found before.

2010-03-01ata: Detect Delkin Devices compact flashBen Gardner1-1/+2
I have a Delkin Devices compact flash card that isn't being recognized using the SATA/PATA drivers. The card is recognized and works with the deprecated ATA drivers. The error I am seeing is: ata1.00: failed to IDENTIFY (device reports invalid type, err_mask=0x0) I tracked it down to ata_id_is_cfa() in include/linux/ata.h. The Delkin card has id[0] set to 0x844a and id[83] set to 0. This isn't what the kernel expects and is probably incorrect. The simplest work-around is to add a check for 0x844a to ata_id_is_cfa().

2010-03-01sata_via: Correctly setup PIO/DMA for pata slave on vt6421.Bart Hartgers1-3/+5
Before only the timings for master were set. Datasheet can be found here: ftp://ftp.vtbridge.org/Docs/Storage/DS_VT6421A_100_CCPL.PDF Surprisingly, a slave drive works without this patch. According to the datasheet, the controller by default derives the DMA mode from the Set Features command issued to a drive. Not sure about the PIO timings, though. The real problem is that the timings for the master effectively are the ones tuned for the slave. If these support different UDMA-settings, there is trouble, especially when the slave supports a higher UDMA than the master. Anyhow, using the same mechanism for both master and slave seems like a good idea.
