rbd: end I/O the entire obj_request on error

2015-05-13T12:14:28Z

commit 082a75dad84d79d1c15ea9e50f31cb4bb4fa7fd6 upstream. When we end I/O struct request with error, we need to pass obj_request->length as @nr_bytes so that the entire obj_request worth of bytes is completed. Otherwise block layer ends up confused and we trip on rbd_assert(more ^ (which == img_request->obj_request_count)); in rbd_img_obj_callback() due to more being true no matter what. We already do it in most cases but we are missing some, in particular those where we don't even get a chance to submit any obj_requests, due to an early -ENOMEM for example. A number of obj_request->xferred assignments seem to be redundant but I haven't touched any of obj_request->xferred stuff to keep this small and isolated.

nbd: fix possible memory leak

Pull block layer fixes from Jens Axboe: "Two smaller fixes for this cycle: - A fixup from Keith so that NVMe compiles without BLK_INTEGRITY, basically just moving the code around appropriately. - A fixup for shm, fixing an oops in shmem_mapping() for mapping with no inode. From Sasha" [ The shmem fix doesn't look block-layer-related, but fixes a bug that happened due to the backing_dev_info removal.. - Linus ] * 'for-linus' of git://git.kernel.dk/linux-block: mm: shmem: check for mapping owner before dereferencing NVMe: Fix for BLK_DEV_INTEGRITY not set

zram: use proper type to update max_used_pages

2015-02-28T17:57:51Z

max_used_pages is defined as atomic_long_t so we need to use unsigned long to keep temporary value for it rather than int which is smaller than unsigned long in a 64 bit system.

NVMe: Fix potential corruption on sync commands

2015-02-19T23:15:38Z

This makes all sync commands uninterruptible and schedules without timeout so the controller either has to post a completion or the timeout recovery fails the command. This fixes potential memory or data corruption from a command timing out too early or woken by a signal. Previously any DMA buffers mapped for that command would have been released even though we don't know what the controller is planning to do with those addresses. Signed-off-by: Keith Busch
