check pr_debug() arguments When DEBUG isn't defined pr_debug() is defined away as an empty macro. By throwing away the arguments we allow completely incorrect code to build. Instead let's make it an empty inline which checks arguments and mark it so gcc can check the format specification. This results in a seemingly insignificant code size increase.

It looks like Zach Brown's patch pr_debug-check-pr_debug-arguments worked as inteded. That is, it doesn't "allow completely incorrect code to build." :). The arm build fails with the following message: CC arch/arm/vfp/vfpsingle.o arch/arm/vfp/vfpsingle.c: In function `__vfp_single_normaliseround': arch/arm/vfp/vfpsingle.c:201: error: `func' undeclared (first use in this function) arch/arm/vfp/vfpsingle.c:201: error: (Each undeclared identifier is reported only once arch/arm/vfp/vfpsingle.c:201: error: for each function it appears in.) make[1]: *** [arch/arm/vfp/vfpsingle.o] Error 1 make: *** [arch/arm/vfp] Error 2 The following patch fixes the issue by using func only when DEBUG is defined.

find_first_set doesn't find the least-significant bit on bigendian machines, so it is really wrong to use it. ffs is closer, but takes an 'int' and we have a 'unsigned long'. So use ffz(~X) to convert a chunksize into a chunkshift. Signed-off-by:

Once upon a time we needed to fixed limit to the number of md devices, probably because we preallocated some array. This need no longer exists, but we still have an arbitrary limit. So remove MAX_MD_DEVS and allow as many devices as we can fit into the 'minor' part of a device number. Also remove some useless noise at init time (which reports MAX_MD_DEVS) and remove MD_THREAD_NAME_MAX which hasn't been used for a while. Signed-off-by:

It is possible to request a 'check' of an md/raid array where the whole array is read and consistancies are reported. This uses the same mechanisms as 'resync' and so reports in the kernel logs that a resync is being started. This understandably confuses/worries people. Also the text in /proc/mdstat suggests a 'resync' is happen when it is just a check. This patch changes those messages to be more specific about what is happening. Signed-off-by:

This is very different from other raid levels and all requests go through a 'stripe cache', and it has congestion management already. Signed-off-by:

raid1, raid10 and multipath don't report their 'congested' status through bdi_*_congested, but should. This patch adds the appropriate functions which just check the 'congested' status of all active members (with appropriate locking). raid1 read_balance should be modified to prefer devices where bdi_read_congested returns false. Then we could use the '&' branch rather than the '|' branch. However that should would need some benchmarking first to make sure it is actually a good idea. Signed-off-by:

Each backing_dev needs to be able to report whether it is congested, either by modulating BDI_*_congested in ->state, or by defining a ->congested_fn. md/raid did neither of these. This patch add a congested_fn which simply checks all component devices to see if they are congested. Signed-off-by:

The error handling routines don't use proper locking, and so two concurrent errors could trigger a problem. So: - use test-and-set and test-and-clear to synchonise the In_sync bits with the ->degraded count - use the spinlock to protect updates to the degraded count (could use an atomic_t but that would be a bigger change in code, and isn't really justified) - remove un-necessary locking in raid5 Signed-off-by: -

Add a new sysfs interface that allows the bitmap of an array to be dirtied. The interface is write-only, and is used as follows: echo "1000" > /sys/block/md2/md/bitmap (dirty the bit for chunk 1000 [offset 0] in the in-memory and on-disk bitmaps of array md2) echo "1000-2000" > /sys/block/md1/md/bitmap (dirty the bits for chunks 1000-2000 in md1's bitmap) This is useful, for example, in cluster environments where you may need to combine two disjoint bitmaps into one (following a server failure, after a secondary server has taken over the array). By combining the bitmaps on the two servers, a full resync can be avoided (This was discussed on the list back on March 18, 2005, "[PATCH 1/2] md bitmap bug fixes" thread). Signed-off-by:

Instead of magic numbers (0,1,2,3) in sb_dirty, we have some flags instead: MD_CHANGE_DEVS Some device state has changed requiring superblock update on all devices. MD_CHANGE_CLEAN The array has transitions from 'clean' to 'dirty' or back, requiring a superblock update on active devices, but possibly not on spares MD_CHANGE_PENDING A superblock update is underway. We wait for an update to complete by waiting for all flags to be clear. A flag can be set at any time, even during an update, without risk that the change will be lost. Stop exporting md_update_sb - isn't needed. Signed-off-by:

I found a problem within device-mapper that occurs in low-mem situations. It was found using a mirror target but I think in theory it would hit any setup that stacks device-mapper devices (like LVM on top of multipath). Since device-mapper core uses the common fs_bioset in clone_bio(), and a private, but still global, bio_set in split_bvec() it is possible that the filesystem and the first level target successfully get bios but the lower level target doesn't because there is no more memory and the pool was drained by upper layers. So the remapping will be stuck forever. To solve this device-mapper core needs to use a private bio_set for each device. Signed-off-by:

This patch is designed to help dm-crypt comply with the new constraints imposed by the following patch in -mm: md-dm-reduce-stack-usage-with-stacked-block-devices.patch Under low memory the existing implementation relies upon waiting for I/O submitted recursively to generic_make_request() completing before the original generic_make_request() call can return. This patch moves the I/O submission to a workqueue so the original generic_make_request() can return immediately. Signed-off-by:
