block: bio-integrity: Copy flags when bio_integrity_payload is cloned
[ Upstream commit b6a4bdcda430e3ca43bbb9cb1d4d4d34ebe15c40 ] Make sure to copy the flags when a bio_integrity_payload is cloned. Otherwise per-I/O properties such as IP checksum flag will not be passed down to the HBA driver. Since the integrity buffer is owned by the original bio, the BIP_BLOCK_INTEGRITY flag needs to be masked off to avoid a double free in the completion path. Fixes: aae7df50190a ("block: Integrity checksum flag") Fixes: b1f01388574c ("block: Relocate bio integrity flags") Reported-by: Saurav Kashyap <skashyap@marvell.com> Tested-by: Saurav Kashyap <skashyap@marvell.com> Signed-off-by: Martin K.
