[PATCH 0/2] Fixup return value for nvme_submit_sync_cmd()

[Hannes Reinecke]

Hi all,

here are two small patches for fixing up the return value of nvme_submit_sync_cmd().
As Keith correctly noted, nvme_submit_sync_cmd() should be returning
an error if the command could not be performed; however, currently
only pci does that.
So the first patch fixes up nvme_cancel_request() to return an -EINTR
on any pending sync commands during reset.
And the second patch adds a new flag 'NVME_REQ_TIMEOUT' to indicate
that a command had been aborted due to a timeout, and translates that
back into -ETIMEDOUT as a return code for nvme_submit_sync_cmd().

As usual, comments and reviews are welcome.

Hannes Reinecke (2):
  nvme: add NVME_REQ_CANCELLED flag in nvme_cancel_request()
  nvme: return -ETIMEDOUT in nvme_submit_sync_cmd()
