* quota: unify quota init condition in setattrDmitry Monakhov2010-05-21
| | | | | | | | | | | | | Quota must being initialized if size or uid/git changes requested. But initialization performed in two different places: in case of i_size file system is responsible for dquot init , but in case of uid/gid init will be called internally in dquot_transfer(). This ambiguity makes code harder to understand. Let's move this logic to one common helper function. Signed-off-by: Dmitry Monakhov <dmonakhov@openvz.org> Signed-off-by: Jan Kara <jack@suse.cz>
* quota: unify ->set_dqblkChristoph Hellwig2010-05-21
| | | | | | | | | | | | | | Pass the larger struct fs_disk_quota to the ->set_dqblk operation so that the Q_SETQUOTA and Q_XSETQUOTA operations can be implemented with a single filesystem operation and we can retire the ->set_xquota operation. The additional information (RT-subvolume accounting and warn counts) are left zero for the VFS quota implementation. Add new fieldmask values for setting the numer of blocks and inodes values which is required for the VFS quota, but wasn't for XFS.

* quota: Make quota stat accounting lockless.Dmitry Monakhov2010-05-21
| | | | | | | | | | | | 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.

* ext2: Add ext2_sb_info s_lock spinlockJan Blunck2010-05-21
| | | | | | | | | | | | | | | | | | | Add a spinlock that protects against concurrent modifications of s_mount_state, s_blocks_last, s_overhead_last and the content of the superblock's buffer pointed to by sbi->s_es. The spinlock is now used in ext2_xattr_update_super_block() which was setting the EXT2_FEATURE_COMPAT_EXT_ATTR flag on the superblock without protection before. Likewise the spinlock is used in ext2_show_options() to have a consistent view of the mount options. This is a preparation patch for removing the BKL from ext2 in the next patch.

| * nilfs2: enlarge s_volume_name member in nilfs_super_blockJiro SEKIBA2010-05-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Current s_volume_name has 16 bytes, which is too small as modern filesystem. s_last_mounted resides just after s_volume_name and has 64 bytes. s_last_mounted is historically came from ext2, but not used in nilfs2 at all. Deleting s_last_mounted member and merging that space with s_volume_name enlarge s_volume_name upto 80 bytes for volume label. When user land tools see the old header for new disk, it will just ignore additional bytes stored in s_last_mounted. While, old disk format has only 16 bytes label, it doesn't affects in case seeing the new header for old disk.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds a field to record the latest checkpoint number in the nilfs_segment_summary structure. This will help to recover the latest checkpoint number from logs on disk. This field is intended for crucial cases in which super blocks have lost pointer to the latest log. Even though this will change the disk format, both backward and forward compatibility is preserved by a size field prepared in the segment summary header.

| * | mtd: nand: support alternate BB marker locations on MLCKevin Cernekee2010-05-13

His original comments follow: This patch adds support for some MLC NAND flashes that place the BB marker in the LAST page of the bad block rather than the FIRST page used for SLC NAND and other types of MLC nand. Lifted from Samsung datasheet for K9LG8G08U0A (1Gbyte MLC NAND): " Identifying Initial Invalid Block(s) All device locations are erased(FFh) except locations where the initial invalid block(s) information is written prior to shipping. The initial invalid block(s) status is defined by the 1st byte in the spare area. Samsung makes sure that the last page of every initial invalid block has non-FFh data at the column address of 2,048. ... " As far as I can tell, this is the same for all Samsung MLC nand, and in fact the samsung bsp for the processor used in our project (s3c6410) actually contained a hack similar to this patch but less portable to enable use of their NAND parts. I discovered this problem when trying to use a Micron NAND which does not used this layout - I wish samsung would put their stuff in main-line to avoid this type of problem. Currently this patch causes all MLC nand with manufacturer codes from Samsung and ST(Numonyx) to use this alternative location, since these are the manufactures that I know of that use this layout.

For instance: Samsung K9GAG08U0M (5-byte sequence): ec d5 14 b6 74 4th byte, bits 1:0 encode the page size: 0=1KiB, 1=2KiB, 2=4KiB, 3=8KiB 4th byte, bits 5:4 encode the block size: 0=64KiB, 1=128KiB, ... 4th byte, bit 6 encodes the OOB size: 0=8B/512B, 1=16B/512B Samsung K9GAG08U0D (6-byte sequence): ec d5 94 29 34 41 4th byte, bits 1:0 encode the page size: 0=2KiB, 1=4KiB, 3=8KiB, 4=rsvd 4th byte, bits 7;5:4 encode the block size: 0=128KiB, 1=256KiB, ... 4th byte, bits 6;3:2 encode the OOB size: 1=128B/page, 2=218B/page This patch uses the new 6-byte scheme if the following conditions are all true: 1) The ID code wraps around after exactly 6 bytes 2) Manufacturer is Samsung 3) 6th byte is zero The patch also extends the maximum OOB size from 128B to 256B.

| * | mtd: fix a huge latency problem in the MTD CFI and LPDDR flash drivers.Stefani Seibold2010-05-10

For example: A flash with 6,5 MB/s bandwidth will cause under ubifs, which request sometimes 128 KiB (the flash erase size), a preemption delay of 20 milliseconds. High priority threads will not be served during this time, regardless whether this threads access the flash or not. This behavior breaks real time. The patch changes all the use of spin_lock operations for xxxx->mutex into mutex operations, which is exact what the name says and means. I have checked the code of the drivers and there is no use of atomic pathes like interrupt or timers. The mtdoops facility will also not be used by this drivers. So it is dave to replace the spin_lock against mutex. There is no performance regression since the mutex is normally not acquired.

| | * | | | | [SCSI] libfc: Move the port_id into lportRobert Love2010-05-16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch creates a port_id member in struct fc_lport. This allows libfc to just deal with fc_lport instances instead of calling into the fc_host to get the port_id. This change helps in only using symbols necessary for operation from the libfc structures. libfc still needs to change the fc_host_port_id() if the port_id changes so the presentation layer (scsi_transport_fc) can provide the user with the correct value, but libfc shouldn't rely on the presentation layer for operational values.

The kernel version is not userspace clean and does not appear to provide anything useable in userland over the (e)glibc version.
