2013-02-18libceph: kill ceph_osdc_create_event() "one_shot" parameterAlex Elder
There is only one caller of ceph_osdc_create_event(), and it provides 0 as its "one_shot" argument. Get rid of that argument and just use 0 in its place. Replace the code in handle_watch_notify() that executes if one_shot is nonzero in the event with a BUG_ON() call. While modifying "osd_client.c", give handle_watch_notify() static scope.

2013-02-13rbd: turn off interrupts for open/remove lockingAlex Elder
This commit: bc7a62ee5 rbd: prevent open for image being removed added checking for removing rbd before allowing an open, and used the same request spinlock for protecting that and updating the open count as is used for the request queue. However it used the non-irq protected version of the spinlocks. Fix that. Signed-off-by: Alex Elder <elder@inktank.com> Reviewed-by: Josh Durgin <josh.durgin@inktank.com>
2013-02-13libceph: don't require r_num_pages for bio requestsAlex Elder
There is a check in the completion path for osd requests that ensures the number of pages allocated is enough to hold the amount of incoming data expected. For bio requests coming from rbd the "number of pages" is not really meaningful (although total length would be). So stop requiring that nr_pages be supplied for bio requests. This is done by checking whether the pages pointer is null before checking the value of nr_pages. Note that this value is passed on to the messenger, but there it's only used for debugging--it's never used for validation. While here, change another spot that used r_pages in a debug message inappropriately, and also invalidate the r_con_filling_msg pointer after dropping a reference to it.

2013-02-13rbd: don't take extra bio reference for osd clientAlex Elder
Currently, if the OSD client finds an osd request has had a bio list attached to it, it drops a reference to it (or rather, to the first entry on that list) when the request is released. The code that added that reference (i.e., the rbd client) is therefore required to take an extra reference to that first bio structure. The osd client doesn't really do anything with the bio pointer other than transfer it from the osd request structure to outgoing (for writes) and ingoing (for reads) messages. So it really isn't the right place to be taking or dropping references. Furthermore, the rbd client already holds references to all bio structures it passes to the osd client, and holds them until the request is completed. So there's no need for this extra reference whatsoever. So remove the bio_put() call in ceph_osdc_release_request(), as well as its matching bio_get() call in rbd_osd_req_create(). This change could lead to a crash if old libceph.ko was used with new rbd.ko. Add a compatibility check at rbd initialization time to avoid this possibilty.

2013-02-13rbd: prevent open for image being removedAlex Elder
An open request for a mapped rbd image can arrive while removal of that mapping is underway. We need to prevent such an open request from succeeding. (It appears that Maciej Galkiewicz ran into this problem.) Define and use a "removing" flag to indicate a mapping is getting removed. Set it in the remove path after verifying nothing holds the device open. And check it in the open path before allowing the open to proceed. Acquire the rbd device's lock around each of these spots to avoid any races accessing the flags and open_count fields.

2013-02-13rbd: don't drop watch requests on completionAlex Elder
When we register an osd request to linger, it means that request will stay around (under control of the osd client) until we've unregistered it. We do that for an rbd image's header object, and we keep a pointer to the object request associated with it. Keep a reference to the watch object request for as long as it is registered to linger. Drop it again after we've removed the linger registration. This resolves: http://tracker.ceph.com/issues/3937 (Note: this originally came about because the osd client was issuing a callback more than once. But that behavior will be changing soon, documented in tracker issue 3967.) Signed-off-by: Alex Elder <elder@inktank.com> Reviewed-by: Josh Durgin <josh.durgin@inktank.com>

2013-02-13rbd: send notify ack asynchronouslyAlex Elder
When we receive notification of a change to an rbd image's header object we need to refresh our information about the image (its size and snapshot context). Once we have refreshed our rbd image we need to acknowledge the notification. This acknowledgement was previously done synchronously, but there's really no need to wait for it to complete. Change it so the caller doesn't wait for the notify acknowledgement request to complete. And change the name to reflect it's no longer synchronous.

2013-02-13rbd: new request tracking codeAlex Elder
This patch fully implements the new request tracking code for rbd I/O requests. Each I/O request to an rbd image will get an rbd_image_request structure allocated to track it. This provides access to all information about the original request, as well as access to the set of one or more object requests that are initiated as a result of the image request. An rbd_obj_request structure defines a request sent to a single osd object (possibly) as part of an rbd image request. An rbd object request refers to a ceph_osd_request structure built up to represent the request; for now it will contain a single osd operation. It also provides space to hold the result status and the version of the object when the osd request completes. An rbd_obj_request structure can also stand on its own. This will be used for reading the version 1 header object, for issuing acknowledgements to event notifications, and for making object method calls. All rbd object requests now complete asynchronously with respect to the osd client--they supply a common callback routine.

2013-01-25rbd: don't retry setting up header watchAlex Elder
When an rbd image is initially mapped a watch event is registered so we can do something if the header object changes. The code that does this currently loops if initiating the watch request results in an ERANGE error. The osds will never return ERANGE, so there's no reason to do this loop, so get rid of it. This resolves: http://tracker.newdream.net/issues/3860 Note that the problem this loop was intended to solve is a race between collecting image header information and setting up the watch on the header object.

2013-01-22cpufreq: Add module aliases for acpi-cpufreqMatthew Garrett
The acpi core will call request_module("acpi-cpufreq") on subsystem init, but this will fail if the module isn't available at that stage of boot. Add some module aliases to ensure that udev can load the module on Intel and AMD systems with the appropriate feature bits - I /think/ that this will also work on VIA systems, but haven't verified that.
