[PATCH v3 0/2] dm crypt: some fixes to support dm-crypt running in softirq context

[Ignat Korchagin]

Changes from v1:
  * 0001: handle memory allocation failure for GFP_ATOMIC

Changes from v2:
  * reordered patches
  * 0002: crypt_convert will be retried from a workqueue, when a crypto request
    allocation fails with GFP_ATOMIC instead of just returning an IO error to
    the user

Ignat Korchagin (2):
  dm crypt: do not wait for backlogged crypto request completion in
    softirq
  dm crypt: use GFP_ATOMIC when allocating crypto requests from softirq
