Subject: [PATCH RFC 0/2] nvme-multipath: additional iopolicies
Date: Wed, 26 Jul 2023 15:23:03 +0200 [thread overview]
Message-ID: <20230726132305.33739-1-hare@suse.de> (raw)
Hi all,
as Ewan raised the issue that we are suffering from a buffer-bloat
problem when using the round-robin I/O scheduler here are additiona
I/O schedulers to improve the situation.
The schedulers are untested, and are compile-tested only.
I just putting them out here as I had several requests for them;
I'm happily improving them upon feedback.
