v4:
* This revision is what German speakers call "das Tüpfelchen auf dem I". "The
icing on the cake" is the English equivalent. Since I like cake and don't
want it to be half-baked, and because I like my metaphors shaken, not
stirred, I went ahead with the extra revision so I could write this message.
* Use g_autoptr(QCryptoBlock) to make the code more concise [Max]
* Use local_err consistently [Max]
* Folded in Max's Reviewed-by tags
v3:
* Move payload offset calculation function to crypto/block.c [Max]
* Zero/unallocated blocks always require disk space on encrypted files [Max]
* Update qemu-iotests 178 output when changing qemu-img measure command-line
options
v2:
* Fix uint64_t <-> size_t type mismatch in block_crypto_measure() so that
32-bit builds pass
This patch series adds qemu-img measure support to the "luks" block driver. We
just need to take into account the LUKS header when sizing the image.
Stefan Hajnoczi (4):
luks: extract qcrypto_block_calculate_payload_offset()
luks: implement .bdrv_measure()
qemu-img: allow qemu-img measure --object without a filename
iotests: add 282 luks qemu-img measure test
