There are now two phases to a suspend in device-mapper - presuspend and postsuspend. This patch removes the single 'suspend' in the logging API and replaces it with 'presuspend' and 'postsuspend' functions to align it better with core device-mapper. A subsequent patch will make use of 'presuspend'. Signed-off-by: NJonathan Brassow <jbrassow@redhat.com> Signed-off-by: NAlasdair G Kergon <agk@redhat.com>

This patch adds retries to the hp hardware handler, and utilizes the MP_RETRY flag of dm-multipath. For now in the hp handler, if we get a pg_init completed with a check condition we just assume we can retry the pg_init command. We make this assumption because of incomplete data on specific check condition code of the HP hardware, and because testing has shown the HP path initialization command to be idempotent. The number of times we retry is settable via the "pg_init_retries" multipath map feature.

This patch allows a failed path group initialisation command to be retried. It adds a generic MP_RETRY flag and a "pg_init_retries" feature to device-mapper multipath which limits the number of retries. 1. A hw handler sends a path initialization command to the storage and the command completes with an error code indicating the command should be retried. 2. The hardware handler calls dm_pg_init_complete() with MP_RETRY set in err_flags to ask the dm multipath core to retry. 3. If the retry limit has not been exceeded, pg_init() is retried. Otherwise fail_path() is called. If you are using the userspace multipath-tools or device-mapper-multipath package, you can set pg_init_retries in the 'device' section of your /etc/multipath.conf file. For example: features "2 pg_init_retries 7" The number of PG retries attempted is reported in the 'dmsetup status' output.

Add post-processing queue (per crypt device) for read operations. Current implementation uses only one queue for all operations and this can lead to starvation caused by many requests waiting for memory allocation.

This patch fixes a bd_mount_sem counter corruption bug in device-mapper. thaw_bdev() should be called only when freeze_bdev() was called for the device. Otherwise, thaw_bdev() will up bd_mount_sem and corrupt the semaphore counter. struct block_device with the corrupted semaphore may remain in slab cache and be reused later. Attached patch will fix it by calling unlock_fs() instead. unlock_fs() will determine whether it should call thaw_bdev() by checking the device is frozen or not. Easy reproducer is: #!/bin/sh while [ 1 ]; do dmsetup --notable create a dmsetup --nolockfs suspend a dmsetup remove a done It's not easy to see the effect of corrupted semaphore. So I have tested with putting printk below in bdev_alloc_inode(): if (atomic_read(&ei->bdev.bd_mount_sem.count) != 1) printk(KERN_DEBUG "Incorrect semaphore count = %d (%p)\n", atomic_read(&ei->bdev.bd_mount_sem.count), &ei->bdev); Without the patch, I saw something like: Incorrect semaphore count = 17 (f2ab91c0) With the patch, the message didn't appear. The bug was introduced in 2.6.16 with this bug fix: commit d9dde59b Date: Fri Feb 24 13:04:24 2006 -0800 [PATCH] dm: missing bdput/thaw_bdev at removal Need to unfreeze and release bdev otherwise the bdev inode with inconsistent state is reused later and cause problem. and backported to 2.6.15.5. It occurs only in free_dev(), which is called only when the dm device is removed. The buggy code is executed only if md->suspended_bdev is non-NULL and that can happen only when the device was suspended without noflush.

Make size of dm_ioctl struct always 312 bytes on all supported architectures. This change retains compatibility with already-compiled code because it uses an embedded offset to locate the payload that follows the structure. On 64-bit architectures there is no change at all; on 32-bit we are increasing the size of dm-ioctl from 308 to 312 bytes. Currently with 32-bit userspace / 64-bit kernel on x86_64 some ioctls (including rename, message) are incorrectly rejected by the comparison against 'param + 1'. This breaks userspace lvrename and multipath 'fail_if_no_path' changes, for example. (BTW Device-mapper uses its own versioning and ignores the ioctl size bits. Only the generic ioctl compat code on mixed arches checks them, and that will continue to accept both sizes for now, but we intend to list 308 as deprecated and eventually remove it.)

lookup() and sillyrename() can race one another because the sillyrename() completion cannot take the parent directory's inode->i_mutex since the latter may be held by whoever is calling dput(). We therefore have little option but to add extra locking to ensure that nfs_lookup() and nfs_atomic_open() do not race with the sillyrename completion. If somebody has looked up the sillyrenamed file in the meantime, we just transfer the sillydelete information to the new dentry.

This patch fixes a regression that was introduced by commit 44dd151d We cannot zero the user page in nfs_mark_uptodate() any more, since a) We'd be modifying the page without holding the page lock b) We can race with other updates of the page, most notably because of the call to nfs_wb_page() in nfs_writepage_setup(). Instead, we do the zeroing in nfs_update_request() if we see that we're creating a request that might potentially be marked as up to date.

When building a specific module before doing a total kernel build it failed because $(MORVERDIR) were missing. Creating the MODVERDIR explicit (independent of KBUILD_MODULES) fixed this.
