This frees up the\nresources used by the target so the core can replace that target with an\nalternative one and then resend the I/O to it. Without this patch the only\nway to change the target in such circumstances involves returning the I/O with\nan error back to the filesystem/application. In the multipath case, this\npatch will let us add new paths for existing I/O to try after all the existing\npaths have failed.\n\n DMF_NOFLUSH_SUSPENDING\n ----------------------\n\nIf the DM_NOFLUSH_FLAG ioctl option is specified at suspend time, the\nDMF_NOFLUSH_SUSPENDING flag is set in md-\u003eflags during dm_suspend(). It\nis always cleared before dm_suspend() returns.\n\nThe flag must be visible while the target is flushing pending I/Os so it\nis set before presuspend where the flush starts and unset after the wait\nfor md-\u003epending where the flush ends.\n\nTarget drivers can check this flag by calling dm_noflush_suspending().\n\n DM_MAPIO_REQUEUE / DM_ENDIO_REQUEUE\n -----------------------------------\n\nA target\u0027s map() function can now return DM_MAPIO_REQUEUE to request the\ndevice mapper core queue the bio.\n\nSimilarly, a target\u0027s end_io() function can return DM_ENDIO_REQUEUE to request\nthe same. This has been labelled \u0027pushback\u0027.\n\nThe __map_bio() and clone_endio() functions in the core treat these return\nvalues as errors and call dec_pending() to end the I/O.\n\n dec_pending\n -----------\n\ndec_pending() saves the pushback request in struct dm_io-\u003eerror. Once all\nthe split clones have ended, dec_pending() will put the original bio on\nthe md-\u003epushback list. Note that this supercedes any I/O errors.\n\nIt is possible for the suspend with DM_NOFLUSH_FLAG to be aborted while\nin progress (e.g. by user interrupt). dec_pending() checks for this and\nreturns -EIO if it happened.\n\n pushdback list and pushback_lock\n --------------------------------\n\nThe bio is queued on md-\u003epushback temporarily in dec_pending(), and after\nall pending I/Os return, md-\u003epushback is merged into md-\u003edeferred in\ndm_suspend() for re-issuing at resume time.\n\nmd-\u003epushback_lock protects md-\u003epushback.\nThe lock should be held with irq disabled because dec_pending() can be\ncalled from interrupt context.\n\nQueueing bios to md-\u003epushback in dec_pending() must be done atomically\nwith the check for DMF_NOFLUSH_SUSPENDING flag. So md-\u003epushback_lock is\nheld when checking the flag. Otherwise dec_pending() may queue a bio to\nmd-\u003epushback after the interrupted dm_suspend() flushes md-\u003epushback.\nThen the bio would be left in md-\u003epushback.\n\nFlag setting in dm_suspend() can be done without md-\u003epushback_lock because\nthe flag is checked only after presuspend and the set value is already\nmade visible via the target\u0027s presuspend function.\n\nThe flag can be checked without md-\u003epushback_lock (e.g. the first part of\nthe dec_pending() or target drivers), because the flag is checked again\nwith md-\u003epushback_lock held when the bio is really queued to md-\u003epushback\nas described above. So even if the flag is cleared after the lockless\ncheckings, the bio isn\u0027t left in md-\u003epushback but returned to applications\nwith -EIO.\n\n Other notes on the current patch\n --------------------------------\n\n- md-\u003epushback is added to the struct mapped_device instead of using\n md-\u003edeferred directly because md-\u003eio_lock which protects md-\u003edeferred is\n rw_semaphore and can\u0027t be used in interrupt context like dec_pending(),\n and md-\u003eio_lock protects the DMF_BLOCK_IO flag of md-\u003eflags too.\n\n- Don\u0027t issue lock_fs() in dm_suspend() if the DM_NOFLUSH_FLAG\n ioctl option is specified, because I/Os generated by lock_fs() would be\n pushed back and never return if there were no valid devices.\n\n- If an error occurs in dm_suspend() after the DMF_NOFLUSH_SUSPENDING\n flag is set, md-\u003epushback must be flushed because I/Os may be queued to\n the list already. (flush_and_out label in dm_suspend())\n\n Test results\n ------------\n\nI have tested using multipath target with the next patch.\n\nThe following tests are for regression/compatibility:\n - I/Os succeed when valid paths exist;\n - I/Os fail when there are no valid paths and queue_if_no_path is not\n set;\n - I/Os are queued in the multipath target when there are no valid paths and\n queue_if_no_path is set;\n - The queued I/Os above fail when suspend is issued without the\n DM_NOFLUSH_FLAG ioctl option. I/Os spanning 2 multipath targets also\n fail.\n\nThe following tests are for the normal code path of new pushback feature:\n - Queued I/Os in the multipath target are flushed from the target\n but don\u0027t return when suspend is issued with the DM_NOFLUSH_FLAG\n ioctl option;\n - The I/Os above are queued in the multipath target again when\n resume is issued without path recovery;\n - The I/Os above succeed when resume is issued after path recovery\n or table load;\n - Queued I/Os in the multipath target succeed when resume is issued\n with the DM_NOFLUSH_FLAG ioctl option after table load. I/Os\n spanning 2 multipath targets also succeed.\n\nThe following tests are for the error paths of the new pushback feature:\n - When the bdget_disk() fails in dm_suspend(), the\n DMF_NOFLUSH_SUSPENDING flag is cleared and I/Os already queued to the\n pushback list are flushed properly.\n - When suspend with the DM_NOFLUSH_FLAG ioctl option is interrupted,\n o I/Os which had already been queued to the pushback list\n at the time don\u0027t return, and are re-issued at resume time;\n o I/Os which hadn\u0027t been returned at the time return with EIO.\n\nSigned-off-by: Kiyoshi Ueda \u003ck-ueda@ct.jp.nec.com\u003e\nSigned-off-by: Jun\u0027ichi Nomura \u003cj-nomura@ce.jp.nec.com\u003e\nSigned-off-by: Alasdair G Kergon \u003cagk@redhat.com\u003e\nCc: dm-devel@redhat.com\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "81fdb096dbcedcc3b94c7e47b59362b5214891e2", "tree": "ce40376d3c16e3105e73d84b0129ab4bfb06dedf", "parents": [ "d2a7ad29a810441e9dacbaddcc2f0c6045390008" ], "author": { "name": "Kiyoshi Ueda", "email": "k-ueda@ct.jp.nec.com", "time": "Fri Dec 08 02:41:07 2006 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@woody.osdl.org", "time": "Fri Dec 08 08:29:09 2006 -0800" }, "message": "[PATCH] dm: ioctl: add noflush suspend\n\nProvide a dm ioctl option to request noflush suspending.
