State transitions in the space of non-allowed states used to be very noisy. Reduce that, since that has little value for the majority of the user base. Signed-off-by: Philipp Reisner <philipp.reisner@linbit.com> Signed-off-by: Lars Ellenberg <lars.ellenberg@linbit.com>

Pretty straight forward conversion. Note that we do round-robin between the drives that have available requests, before we simply used the drive that the IO scheduler told us to. Since the IO scheduler doesn't care about multiple devices per queue, the resulting sort would not have made sense. Fixed by Vivek to get rid of a double lock problem in set_next_request() Signed-off-by: Jens Axboe <jaxboe@fusionio.com> Signed-off-by: Vivek Goyal <vgoyal@redhat.com>

Create /sys/block/loopX/loop directory and provide these attributes: - backing_file - autoclear - offset - sizelimit This loop directory is present only if loop device is configured. To be used in util-linux-ng (and possibly elsewhere like udev rules) where code need to get loop attributes from kernel (and not store duplicate info in userspace). Moreover loop ioctls are not even able to provide full backing file info because of buffer limits. Signed-off-by: Milan Broz <mbroz@redhat.com> Signed-off-by: Jens Axboe <jaxboe@fusionio.com>

Commit ebf8aa44 ("radix-tree: omplement function radix_tree_range_tag_if_tagged") does not safely set tags on on intermediate tree nodes. The code walks down the tree setting tags before it has fully resolved the path to the leaf under the assumption there will be a leaf slot with the tag set in the range it is searching. Unfortunately, this is not a valid assumption - we can abort after setting a tag on an intermediate node if we overrun the number of tags we are allowed to set in a batch, or stop scanning because we we have passed the last scan index before we reach a leaf slot with the tag we are searching for set. As a result, we can leave the function with tags set on intemediate nodes which can be tripped over later by tag-based lookups. The result of these stale tags is that lookup may end prematurely or livelock because the lookup cannot make progress. The fix for the problem involves reocrding the traversal path we take to the leaf nodes, and only propagating the tags back up the tree once the tag is set in the leaf node slot. We are already recording the path for efficient traversal, so there is no additional overhead to do the intermediately node tag setting in this manner. This fixes a radix tree lookup livelock triggered by the new writeback sync livelock avoidance code introduced in commit f446daae ("mm: implement writeback livelock avoidance using page tagging").

Commit f446daae ("mm: implement writeback livelock avoidance using page tagging") introduced a new radix tree tag, increasing the number of tags in each node from 2 to 3. It did not, however, fix up the code in radix_tree_node_rcu_free() that cleans up after radix_tree_shrink() and hence could leave stray tags set in the new tag array. The result is that the livelock avoidance code added in the the above commit would hit stale tags when doing tag based lookups, resulting in livelocks when trying to traverse the tree. Fix this problem in radix_tree_node_rcu_free() so it doesn't happen again in the future by using a loop to walk all the tags up to RADIX_TREE_MAX_TAGS to clear the stray tags radix_tree_shrink() leaves behind.
