Subject: [RFC PATCH v2 0/4] block layer change necessary for bcache zoned device support
Date: Sat, 16 May 2020 11:54:30 +0800 [thread overview]
Message-ID: <20200516035434.82809-1-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.
Thanks for the review comments from Keith Busch, I fix the typo and post
the v2 series for your review and comments.
Thank you all in advance.
Coly Li
