The name of 'struct pm_ops' suggests that it is related to the power management in general, but in fact it is only related to suspend. Moreover, its name should indicate what this structure is used for, so it seems reasonable to change it to 'struct platform_suspend_ops'. In that case, the name of the global variable of this type used by the PM core and the names of related functions should be changed accordingly. Signed-off-by: NRafael J.

Move the definition of 'struct pm_ops' and related functions from <linux/pm.h> to <linux/suspend.h> . There are, at least, the following reasons to do that: * 'struct pm_ops' is specifically related to suspend and not to the power management in general. * As long as 'struct pm_ops' is defined in <linux/pm.h>, any modification of it causes the entire kernel to be recompiled, which is unnecessary and annoying. * Some suspend-related features are already defined in <linux/suspend.h>, so it is logical to move the definition of 'struct pm_ops' into there. * 'struct hibernation_ops', being the hibernation-related counterpart of 'struct pm_ops', is defined in <linux/suspend.h> .

This has not been any serious user of this ill conceived thing since the original invention in like '95 so I recently deleted this from everywhere except the last instance in logo.c. This patch removes the last two instances in logo.c. They conditions were not useful anyway as when compiled in they would always evaluate as true.

The patch - Includes the call to capilib_data_b3_req in the spinlock. This routine in turn calls the offending mq_enqueue routine that triggered the freeze if not locked. This should also fix other indicators of incosistent capilib_msgidqueue list, that trigger messages like: Oct 5 03:05:57 BERL0 kernel: kcapi: msgid 3019 ncci 0x30301 not on queue that we saw several times a day (usually several in a row). - Fixes all occurrences of c4_dispatch_tx to be called with active spinlock, there were some instances where no lock was active. Mostly these are in very infrequently called routines, so the additional performance penalty is minimal.

When resizing online, setup_new_group_blocks attempts to reserve a potentially very large transaction, depending on the current filesystem geometry. For some journal sizes, there may not be enough room for this transaction, and the online resize will fail. The patch below resizes & restarts the transaction as necessary while setting up the new group, and should work with even the smallest journal. Tested with something like: [root@newbox ~]# dd if=/dev/zero of=fsfile bs=1024 count=32768 [root@newbox ~]# mkfs.ext3 -b 1024 fsfile 16384 [root@newbox ~]# mount -o loop fsfile mnt/ [root@newbox ~]# resize2fs /dev/loop0 resize2fs 1.40.2 (12-Jul-2007) Filesystem at /dev/loop0 is mounted on /root/mnt; on-line resizing required old desc_blocks = 1, new_desc_blocks = 1 Performing an on-line resize of /dev/loop0 to 32768 (1k) blocks. resize2fs: No space left on device While trying to add group #2 [root@newbox ~]# dmesg | tail -n 1 JBD: resize2fs wants too many credits (258 > 256) [root@newbox ~]# With the below change, it works.

This feature relaxes check restrictions on where each block groups meta data is located within the storage media. This allows for the allocation of bitmaps or inode tables outside the block group boundaries in cases where bad blocks forces us to look for new blocks which the owning block group can not satisfy. This will also allow for new meta-data allocation schemes to improve performance and scalability. Signed-off-by: NJose R.

In pass1 of e2fsck, every inode table in the fileystem is scanned and checked, regardless of whether it is in use. This is this the most time consuming part of the filesystem check. The unintialized block group feature can greatly reduce e2fsck time by eliminating checking of uninitialized inodes. With this feature, there is a a high water mark of used inodes for each block group. Block and inode bitmaps can be uninitialized on disk via a flag in the group descriptor to avoid reading or scanning them at e2fsck time. A checksum of each group descriptor is used to ensure that corruption in the group descriptor's bit flags does not cause incorrect operation. The feature is enabled through a mkfs option mke2fs /dev/ -O uninit_groups A patch adding support for uninitialized block groups to e2fsprogs tools has been posted to the linux-ext4 mailing list. The patches have been stress tested with fsstress and fsx. In performance tests testing e2fsck time, we have seen that e2fsck time on ext3 grows linearly with the total number of inodes in the filesytem. In ext4 with the uninitialized block groups feature, the e2fsck time is constant, based solely on the number of used inodes rather than the total inode count. Since typical ext4 filesystems only use 1-10% of their inodes, this feature can greatly reduce e2fsck time for users. With performance improvement of 2-20 times, depending on how full the filesystem is. The attached graph shows the major improvements in e2fsck times in filesystems with a large total inode count, but few inodes in use. In each group descriptor if we have EXT4_BG_INODE_UNINIT set in bg_flags: Inode table is not initialized/used in this group. So we can skip the consistency check during fsck. EXT4_BG_BLOCK_UNINIT set in bg_flags: No block in the group is used. So we can skip the block bitmap verification for this group. We also add two new fields to group descriptor as a part of uninitialized group patch. __le16 bg_itable_unused; /* Unused inodes count */ __le16 bg_checksum; /* crc16(sb_uuid+group+desc) */ bg_itable_unused: If we have EXT4_BG_INODE_UNINIT not set in bg_flags then bg_itable_unused will give the offset within the inode table till the inodes are used. This can be used by fsck to skip list of inodes that are marked unused. bg_checksum: Now that we depend on bg_flags and bg_itable_unused to determine the block and inode usage, we need to make sure group descriptor is not corrupt. We add checksum to group descriptor to detect corruption. If the descriptor is found to be corrupt, we mark all the blocks and inodes in the group used.
