Since Linux doesn't have a user API to issue zone append operations to zoned devices from user space, the file-posix driver is modified to add zone append emulation using regular writes. To do this, the file-posix driver tracks the wp location of all zones of the device. It uses an array of uint64_t. The most significant bit of each wp location indicates if the zone type is conventional zones. The zones wp can be changed due to the following operations issued: - zone reset: change the wp to the start offset of that zone - zone finish: change to the end location of that zone - write to a zone - zone append Signed-off-by: Sam Li <faithilikerun@gmail.com> Message-id: 20230508051510.177850-2-faithilikerun@gmail.com [Fix errno propagation from handle_aiocb_zone_mgmt() --Stefan] Signed-off-by: Stefan Hajnoczi <stefanha@redhat.com> |
