If an DMA channel was active at suspend, then ensure that it is correctly reconfigured when the system resumes. Note, the previous policy was for each driver to handle their own reconfiguration on resume. The policy has been changed to make the individual driver's job easier.

The current S3C24XX DMA code does not allow for an peripheral that has one channel for RX and another for TX. This patch adds a per-cpu dma operation to select the transmit or receive channel, and adds support to the S3C2412 for the seperate DMA channels for TX and RX.

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.

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().

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: NTao Ma <tao.ma@oracle.com> Signed-off-by: NMark Fasheh <mark.fasheh@oracle.com>

-
由 Mark Fasheh 提交于
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: NSunil Mushran <sunil.mushran@oracle.com> Signed-off-by: NMark Fasheh <mark.fasheh@oracle.com>
