I have been using your module and so far it has been working great. Thank you for your work in this.
An issue that I have encountered:
a. When a HDD ( The cached block device ) is dropped off (For example: The disk is dead or someone pulled the disk out), the system will encounter a flood of kernel/syslog messages when will then be filling up the /var/log very quickly.
The host would then require a sysrq reboot due to /var/log being filled up with the following messages:
I am not sure whether if this would be the right place to be raising this and if this is expected
I was thinking that this issue (The flooding of the kernel messages) could be because when a cached block device is dropped suddenly, writeboost would still continue to try flushing the data back to the failed cached block device
A solution that I was thinking of, is to either suppress/filter out the "blk_partition_remap" messages so that the /var/log doesn't get filled up at least

lsblk (wb_sdi, wb_sdj are the writeboost devices and a lvm volume is created on top of it):
writeboost settings:
