Check if the sleep command returns due to a pending interrupt in the standby unit. If this happens, try and ack the IRQ before re-trying the resume. It is currently unclear whether the resume can be backed out of at this stage as this could cause a problem with level based interrupts. Signed-off-by:

If the watchdog reset fails and we decided to take the jump to zero approach, allow 50ms for the UARTS to drain the FIFOs before calling into a bootloader that may flush the output. Also reduece the waits and the timeout values as 5 seconds is rather long. Signed-off-by:

If we know a buffer_head is non-null, then brelse() is unnecessary and put_bh() can be used instead. Also, an explicit check for NULL is unnecessary when using brelse(). This patch only covers buffer_head_io.c and resize.c, which have recently added code which exhibits this problem. Signed-off-by:Mark Fasheh <mark.fasheh@oracle.com>

Currently the process of dlm join contains 2 steps: query join and assert join. After query join, the joined node will set its joining_node. So if the joining node happens to panic before the 2nd step, the joined node will fail to clear its joining_node flag because that node isn't in the domain map. It at least cause 2 problems. 1. All the new join request will fail. So no new node can mount the volume. 2. The joined node can't umount the volume since during the umount process it has to wait for the joining_node to be unknown. So the umount will be hanged. The solution is to clear the joining_node before we check the domain map. Signed-off-by:

Lots of people are having trouble with the default timeouts, which are too low. These new values are derived from an informal survey taken on ocfs2-users, as well as data from bug reports. This should reduce the amount of cluster disconnects and subsequent fencing seen during normal workloads. Signed-off-by:

Hook up ocfs2_flock(), using the new flock lock type in dlmglue.c. A new mount option, "localflocks" is added so that users can revert to old functionality as need be. Signed-off-by: -
Mark Fasheh authored
This adds a new dlmglue lock type which is intended to back flock() requests. Since these locks are driven from userspace, usage rules are much more liberal than the typical Ocfs2 internal cluster lock. As a result, we can't make use of most dlmglue features - lock caching and lock level optimizations in particular. Additionally, userspace is free to deadlock itself, so we have to deal with that in the same way as the rest of the kernel - by allowing a signal to abort a lock request. In order to keep ocfs2_cluster_lock() complexity down, ocfs2_file_lock() does it's own dlm coordination. We still use the same helper functions though, so duplicated code is kept to a minimum.

Local alloc is a performance optimization in ocfs2 in which a node takes a window of bits from the global bitmap and then uses that for all small local allocations. This window size is fixed to 8MB currently. This patch allows users to specify the window size in MB including disabling it by passing in 0. If the number specified is too large, the fs will use the default value of 8MB. mount -o localalloc=X /dev/sdX /mntpoint Signed-off-by:

Mostly taken from ext3. This allows the user to set the jbd commit interval, in seconds. The default of 5 seconds stays the same, but now users can easily increase the commit interval. Typically, this would be increased in order to benefit performance at the expense of data-safety. Signed-off-by: -

Check that an online resize is being driven by a user with permission to change system resource limits. Signed-off-by: -
Tao Ma authored
This patch adds the ability for a userspace program to request that a properly formatted cluster group be added to the main allocation bitmap for an Ocfs2 file system. The request is made via an ioctl, OCFS2_IOC_GROUP_ADD. On a high level, this is similar to ext3, but we use a different ioctl as the structure which has to be passed through is different. During an online resize, tunefs.ocfs2 will format any new cluster groups which must be added to complete the resize, and call OCFS2_IOC_GROUP_ADD on each one. Kernel verifies that the core cluster group information is valid and then does the work of linking it into the global allocation bitmap. Signed-off-by:
