[PATCH 0/5] block layer: permission API refactoring in preparation

[Emanuele Giuseppe Esposito]

This serie aims to refactoring and fixing permission API related bugs that came
up in the serie "block layer: split block APIs in global state and I/O".
In that serie, we are splitting all block layer headers in
Global State (GS) APIs, holding always the BQL and running in the
main loop, and I/O running in iothreads.

The patches in this serie are taken from v6 of the API split,
to reduce its size and apply these fixes independently.

Patches 1 and 2 take care of crypto and amend jobs, since they
incorrectly use the permission API also in iothreads.
Patches 3-4-5 take care of bdrv_invalidate_cache and callers,
since this function checks too for permisisons while being
called by an iothread.

Emanuele Giuseppe Esposito (5):
  crypto: perform permission checks under BQL
  crypto: distinguish between main loop and I/O in
    block_crypto_amend_options_generic_luks
  block: introduce bdrv_activate
  block: rename bdrv_invalidate_cache_all, blk_invalidate_cache and
    test_sync_op_invalidate_cache
  block: move BQL logic of bdrv_co_invalidate_cache in bdrv_activate
