Subject: [PATCH v11 20/40] btrfs: use bio_add_zone_append_page for zoned btrfs
Date: Tue, 22 Dec 2020 12:49:13 +0900 [thread overview]
Message-ID: <bf6e2912dfc3062a914fb4c1ea5e550ac514725e.1608608848.git.naohiro.aota@wdc.com> (raw)
In-Reply-To: <06add214bc16ef08214de1594ecdfcc4cdcdbd78.1608608848.git.naohiro.aota@wdc.com>
Zoned device has its own hardware restrictions e.g. max_zone_append_size
when using REQ_OP_ZONE_APPEND. To follow the restrictions, use
bio_add_zone_append_page() instead of bio_add_page(). We need target device
to use bio_add_zone_append_page(), so this commit reads the chunk
information to memoize the target device to btrfs_io_bio(bio)->device.
Currently, zoned btrfs only supports SINGLE profile. In the feature,
btrfs_io_bio can hold extent_map and check the restrictions for all the
devices the bio will be mapped.
