In commit ea455f8a, we moved the dentry lock put process into ocfs2_wq. This causes problems during umount because ocfs2_wq can drop references to inodes while they are being invalidated by invalidate_inodes() causing all sorts of nasty things (invalidate_inodes() ending in an infinite loop, "Busy inodes after umount" messages etc.). We fix the problem by stopping ocfs2_wq from doing any further releasing of inode references on the superblock being unmounted, wait until it finishes the current round of releasing and finally cleaning up all the references in dentry_lock_list from ocfs2_put_super(). The issue was tracked down by Tao Ma <tao.ma@oracle.com>. Signed-off-by:

In normal tree rotation left process, we will never touch the tree branch above subtree_index and ocfs2_extend_rotate_transaction doesn't reserve the credits for them either. But when we want to delete the rightmost extent block, we have to update the rightmost records for all the rightmost branch(See ocfs2_update_edge_lengths), so we have to allocate extra credits for them. What's more, we have to access them also. Signed-off-by:

ocfs2_get_block() does no allocation. Hole filling for writes should have happened farther up in the call chain. We detect this case and print an error, but we then continue with the function. We should be exiting immediately. Signed-off-by:

If the mount fails for any reason, ocfs2_dismount_volume calls ocfs2_orphan_scan_stop. It requires that ocfs2_orphan_scan_init be called to setup the mutex and work queues, but that doesn't happen if the mount has failed and we oops accessing an uninitialized work queue. This patch splits the init and startup of the orphan scan, eliminating the oops. Signed-off-by:

Alex found that specjbb2005 still can not run with hugepages on an x86-64 machine. This only happens when numa is not compiled in. The root cause: node_set_state will not set it back for us in that case, so don't clear that when numa is not select in config [ v2: use node_clear_state instead ] Reported-and-Tested-by:

This fixes the ppp problems and various other issues with call locking caused by one side of a pty called in one locking context trying to match another with differing rules on the other side. We also get a big slack space to work with that means we can bury the flow control deadlock case for any conceivable real world situation. Signed-off-by:

After some API change, intel_iommu_unmap_range() introduced a assumption that parameter size != 0, otherwise the dma_pte_clean_range() would have a overflowed argument. But the user like KVM don't have this assumption before, then some BUG() triggered. Fix it by ignoring size = 0. Signed-off-by:

The f_dev in _request_firmware() is allocated via the fw_setup_device() and fw_register_device() calls and its class set to firmware_class (the class release function is fw_dev_release). Commit 6acf70f0 replaced the kfree(dev) in fw_dev_release() with a put_device() call but my understanding is that the release function is called via put_device -> kobject_put -> kref_put -> koject_release etc. and it should call kfree since it's the last to see this device structure alive. Because of that, the _request_firmware() function on its -ENOENT error path only calls device_unregister(f_dev) which would eventually call fw_dev_release() but there is no kfree (the subsequent put_device call would just make the kref negative).

Serio ports are not being restarted any longer because resume operations after hibernate do nothing, since the device has not been marked as suspended. This happens because suspend is only considering the SUSPEND event but not the FREEZE event. Note that this driver has still to migrate to dev_pm_ops, but this fixes this particular bug now.

Current implementation of spin_event_timeout can be interrupted by an IRQ or context switch after testing the condition, but before checking the timeout. This can cause the loop to report a timeout when the condition actually became true in the middle. This patch adds one final check of the condition upon exit of the loop if the last test of the condition was still false. Signed-off-by:
