2010-06-11ALSA: usb-audio: fix UAC2 control value queriesDaniel Mack1-5/+14
For RANGE requests, we should only query as much bytes as we're in fact interested in. For CUR requests, we shouldn't confuse the firmware with an overlong request but just ask for 2 bytes. This might need fixing in the future as it's not entirely clear when to dispatch 1-byte, 2-byte and 4-byte request blocks. For now, we assume everything is coded in 16bit - this works for all firmware implementations I've seen.

refs can be used with uninitialized data if btrfs_lookup_extent_info() fails on the first pass through the loop.

2010-06-11Btrfs: fix loop device on top of btrfsMiao Xie1-0/+1
We cannot use the loop device which has been connected to a file in the btrf The reproduce steps is following: # dd if=/dev/zero of=vdev0 bs=1M count=1024 # losetup /dev/loop0 vdev0 # mkfs.btrfs /dev/loop0 ... failed to zero device start -5 The reason is that the btrfs don't implement either ->write_begin or ->write the VFS API, so we fix it by setting ->write to do_sync_write().

2010-06-11writeback: fix pin_sb_for_writebackChristoph Hellwig1-8/+10
We need to check for s_instances to make sure we don't bother working against a filesystem that is beeing unmounted, and we need to call put_super to make sure a superblock is freed when we race against umount.

2010-06-11writeback: add missing requeue_io in writeback_inodes_wbChristoph Hellwig1-1/+3
In "writeback: fix writeback_inodes_wb from writeback_inodes_sb" I accidentally removed the requeue_io if we need to skip a superblock because we can't pin it.

2010-06-11writeback: simplify and split bdi_start_writebackChristoph Hellwig3-17/+24

2010-06-11writeback: fix writeback_inodes_wb from writeback_inodes_sbChristoph Hellwig1-38/+23
When we call writeback_inodes_wb from writeback_inodes_sb we always have s_umount held, which currently makes the whole operation a no-op. But if we are called to write out inodes for a specific superblock we always have s_umount held, so replace the incorrect logic checking for WB_SYNC_ALL which only worked by coincidence with the proper check for an explicit superblock argument.

2010-06-11writeback: enforce s_umount locking in writeback_inodes_sbChristoph Hellwig2-0/+8
Make sure that not only sync_filesystem but all callers of writeback_inodes_sb have the superblock protected against remount. As-is this disables all functionality for these callers, but the next patch relies on this locking to fix writeback_inodes_sb for sync_filesystem.

2010-06-11writeback: queue work on stack in writeback_inodes_sbChristoph Hellwig1-19/+21
If we want to rely on s_umount in the caller we need to wait for completion of the I/O submission before returning to the caller. Refactor bdi_sync_writeback into a bdi_queue_work_onstack helper and use it for this case. Signed-off-by: Christoph Hellwig <[email protected]> Signed-off-by: Jens Axboe <[email protected]>
2010-06-11writeback: fix writeback completion notificationsChristoph Hellwig1-50/+15
The code dealing with bdi_work->state and completion of a bdi_work is a major mess currently. This patch makes sure we directly use one set of flags to deal with it, and use it consistently, which means: - always notify about completion from the rcu callback. We only ever wait for it from on-stack callers, so this simplification does not even cause a theoretical slowdown currently. It also makes sure we don't miss out on the notification if we ever add other callers to wait for it. - make earlier completion notification depending on the on-stack allocation, not the sync mode. If we introduce new callers that want to do WB_SYNC_NONE writeback from on-stack callers this will be nessecary. Also rename bdi_wait_on_work_clear to bdi_wait_on_work_done and inline a few small functions into their only caller to make the code understandable.

2010-06-10net: deliver skbs on inactive slaves to exact matchesJohn Fastabend3-6/+20
Currently, the accelerated receive path for VLAN's will drop packets if the real device is an inactive slave and is not one of the special pkts tested for in skb_bond_should_drop(). This behavior is different then the non-accelerated path and for pkts over a bonded vlan. For example, vlanx -> bond0 -> ethx will be dropped in the vlan path and not delivered to any packet handlers at all. However, bond0 -> vlanx -> ethx and bond0 -> ethx will be delivered to handlers that match the exact dev, because the VLAN path checks the real_dev which is not a slave and netif_recv_skb() doesn't drop frames but only delivers them to exact matches. This patch adds a sk_buff flag which is used for tagging skbs that would previously been dropped and allows the skb to continue to skb_netif_recv(). Here we add logic to check for the deliver_no_wcard flag and if it is set only deliver to handlers that match exactly. This makes both paths above consistent and gives pkt handlers a way to identify skbs that come from inactive slaves. Without this patch in some configurations skbs will be delivered to handlers with exact matches and in others be dropped out right in the vlan path. I have tested the following 4 configurations in failover modes and load balancing modes. # bond0 -> ethx # vlanx -> bond0 -> ethx # bond0 -> vlanx -> ethx # bond0 -> ethx | vlanx -> -- Signed-off-by: John Fastabend <[email protected]> Signed-off-by: David S.

2010-06-10perf/tracing: Fix regression of perf losing kprobe eventsSteven Rostedt1-1/+3
With the addition of the code to shrink the kernel tracepoint infrastructure, we lost kprobes being traced by perf. The reason is that I tested if the "tp_event->class->perf_probe" existed before enabling it. This prevents "ftrace only" events (like the function trace events) from being enabled by perf. Unfortunately, kprobe events do not use perf_probe. This causes kprobes to be missed by perf. To fix this, we add the test to see if "tp_event->class->reg" exists as well as perf_probe. Normal trace events have only "perf_probe" but no "reg" function, and kprobes and syscalls have the "reg" but no "perf_probe". The ftrace unique events do not have either, so this is a valid test. If a kprobe or syscall is not to be probed by perf, the "reg" function is called anyway, and will return a failure and prevent perf from probing it.

2010-06-10ceph: try to send partial cap release on cap message on missing inodeSage Weil3-5/+9
If we have enough memory to allocate a new cap release message, do so, so that we can send a partial release message immediately.
