[RFC PATCH 0/4] block layer change necessary for bcache zoned device support

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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.
