| * rbd: use watch/notify for changes in rbd headerYehuda Sadeh2011-03-221-26/+335
| | | | | | | | | | | | | | | | | | Send notifications when we change the rbd header (e.g. create a snapshot) and wait for such notifications. This allows synchronizing the snapshot creation between different rbd clients/rools. Signed-off-by: Yehuda Sadeh <yehuda@hq.newdream.net> Signed-off-by: Sage Weil <sage@newdream.net>
| * libceph: add lingering request and watch/notify event frameworkYehuda Sadeh2011-03-223-12/+426
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Lingering requests are requests that are sent to the OSD normally but tracked also after we get a successful request. This keeps the OSD connection open and resends the original request if the object moves to another OSD. The OSD can then send notification messages back to us if another client initiates a notify. This framework will be used by RBD so that the client gets notification when a snapshot is created by another node or tool.

| * libceph: fix osd request queuing on osdmap updatesSage Weil2011-03-212-135/+125
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If we send a request to osd A, and the request's pg remaps to osd B and then back to A in quick succession, we need to resend the request to A. The old code was only calling kick_requests after processing all incremental maps in a message, so it was very possible to not resend a request that needed to be resent. This would make the osd eventually time out (at least with the current default of osd timeouts enabled). The correct approach is to scan requests on every map incremental. This patch refactors the kick code in a few ways: - all requests are either on req_lru (in flight), req_unsent (ready to send), or req_notarget (currently map to no up osd) - mapping always done by map_request (previous map_osds) - if the mapping changes, we requeue. requests are resent only after all map incrementals are processed. - some osd reset code is moved out of kick_requests into a separate function - the "kick this osd" functionality is moved to kick_osd_requests, as it is unrelated to scanning for request->pg->osd mapping changes Signed-off-by: Sage Weil <sage@newdream.net>
| * ceph: preserve I_COMPLETE across renameSage Weil2011-03-151-8/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | d_move puts the renamed dentry at the end of d_subdirs, screwing with our cached dentry directory offsets. We were just clearing I_COMPLETE to avoid any possibility of trouble. However, assigning the renamed dentry an offset at the end of the directory (to match it's new d_subdirs position) is sufficient to maintain correct behavior and hold onto I_COMPLETE. This is especially important for workloads like rsync, which renames files into place. Before, we would lose I_COMPLETE and do MDS lookups for each file. With this patch we only talk to the MDS on create and rename. Signed-off-by: Sage Weil <sage@newdream.net>

* | tty: stop using "delayed_work" in the tty layerLinus Torvalds2011-03-224-16/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Using delayed-work for tty flip buffers ends up causing us to wait for the next tick to complete some actions. That's usually not all that noticeable, but for certain latency-critical workloads it ends up being totally unacceptable. As an extreme case of this, passing a token back-and-forth over a pty will take two ticks per iteration, so even just a thousand iterations will take 8 seconds assuming a common 250Hz configuration. Avoiding the whole delayed work issue brings that ping-pong test-case down to 0.009s on my machine. In more practical terms, this latency has been a performance problem for things like dive computer simulators (simulating the serial interface using the ptys) and for other environments (Alan mentions a CP/M emulator).

The reason why we have to do that is explain by the commit message of fef5ba797991f9335bcfc295942b684f9bf613a1: "Xen requires that all pages containing pagetable entries to be mapped read-only. If pages used for the initial pagetable are already mapped then we can change the mapping to RO. However, if they are initially unmapped, we need to make sure that when they are later mapped, they are also mapped RO. ..SNIP.. the pagetable setup code early_ioremaps the pages to write their entries, so we must make sure that mappings created in the early_ioremap fixmap area are mapped RW. (Those mappings are removed before the pages are presented to Xen as pagetable pages.)" We accomplish all this in mask_rw_pte by mapping RO all the pages mapped using early_ioremap apart from the last one that has been allocated because it is not a page table page yet (it has not been hooked into the page tables yet).

| * | x86: Cleanup highmap after brk is concludedYinghai Lu2011-03-193-30/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Now cleanup_highmap actually is in two steps: one is early in head64.c and only clears above _end; a second one is in init_memory_mapping() and tries to clean from _brk_end to _end. It should check if those boundaries are PMD_SIZE aligned but currently does not. Also init_memory_mapping() is called several times for numa or memory hotplug, so we really should not handle initial kernel mappings there. This patch moves cleanup_highmap() down after _brk_end is settled so we can do everything in one step. Also we honor max_pfn_mapped in the implementation of cleanup_highmap.

In case of a real timeout I changed the error code to I2C_RETRY so we retry the transfer.

IRQF_DISABLED is removed because it is a NOP allready and scheduled for removal.

| | * | | | | | i2c-pxa2xx: Add PCI support for PXA I2C controllerSebastian Andrzej Siewior2011-03-214-5/+206
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Sodaville I2C controller is almost the same as found on PXA2xx. The difference: - the register are at a different offset - no slave support The PCI probe code adds three platform devices which are probed then by the platform code. The X86 part also adds dummy clock defines because we don't have HW clock support.

This change should make no functional change to the PXA code. The move is verified by building the following defconfigs: cm_x2xx_defconfig corgi_defconfig em_x270_defconfig ezx_defconfig imote2_defconfig pxa3xx_defconfig spitz_defconfig zeus_defconfig raumfeld_defconfig magician_defconfig mmp2_defconfig pxa168_defconfig pxa910_defconfig Signed-off-by: Sebastian Andrzej Siewior <bigeasy@linutronix.de> Signed-off-by: Dirk Brandewie <dirk.brandewie@gmail.com> Signed-off-by: Ben Dooks <ben-linux@fluff.org>
