Subject: [PATCH v12 0/3] bio: control bio max size
Date: Fri, 4 Jun 2021 14:03:21 +0900 [thread overview]
Message-ID: <20210604050324.28670-1-nanich.lee@samsung.com> (raw)
In-Reply-To: CGME20210604052157epcas1p2e5eebb52d08b06174696290e11fdd5a4@epcas1p2.samsung.com
bio size can grow up to 4GB after muli-page bvec has been enabled.
But sometimes large size of bio would lead to inefficient behaviors.
Control of bio max size will be helpful to improve inefficiency.
blk_queue_max_bio_bytes() is added to enable be set the max_bio_bytes in
each driver layer. And max_bio_bytes sysfs is added to show current
max_bio_bytes for each request queue.
bio size can be controlled via max_bio_bytes.
Changheun Lee (3):
bio: control bio max size
blk-sysfs: add max_bio_bytes
ufs: set max_bio_bytes with queue max sectors
