Subject: [RFC PATCH 0/4] block layer change necessary for bcache zoned device support
Date: Sat, 16 May 2020 00:31:53 +0800	[thread overview]
Message-ID: <20200515163157.72796-1-colyli@suse.de> (raw)

Hi folks,

Recently I am working on supprt bcache to be created on zoned devices
e.g. host managed SMR hard drives, then frequent random READ I/Os on
these SMR drives can be accelerated.

To make the bcache code work correctly, there are some small but maybe
important changes of block layer code are necessary. Here I post these
patches for your review and comments.

Thank you all in advance.

Coly Li
