Subject: [PATCH 13/13] block: Simplify zone write plug BIO abort
Date: Tue, 30 Apr 2024 21:51:31 +0900	[thread overview]
Message-ID: <20240430125131.668482-14-dlemoal@kernel.org> (raw)
In-Reply-To: <20240430125131.668482-1-dlemoal@kernel.org>

When BIOs plugged in a zone write plug are aborted,
blk_zone_wplug_bio_io_error() clears the BIO BIO_ZONE_WRITE_PLUGGING
flag so that bio_io_error(bio) does not end up calling
blk_zone_write_plug_bio_endio() and we thus need to manually drop the
reference on the zone write plug held by the aborted BIO.

Move the call to disk_put_zone_wplug() that is alwasy following the call
to blk_zone_wplug_bio_io_error() inside that function to simplify the
code.
