Subject: block: Clear BIO_EMULATES_ZONE_APPEND flag on BIO completion
|
|
|
|
When blk_zone_write_plug_bio_endio() is called for a regular write BIO
|
|
used to emulate a zone append operation, that is, a BIO flagged with
|
|
BIO_EMULATES_ZONE_APPEND, the BIO operation code is restored to the
|
|
original REQ_OP_ZONE_APPEND but the BIO_EMULATES_ZONE_APPEND flag is not
|
|
cleared. Clear it to fully return the BIO to its orginal definition.
|
|
|
