Hello all dm developers
have you seen latest kernel projects by Mark Ruijter at www.lessfs.com? 
he has an write-only caching block device with barrier correctness 
(EPRD) and one tiered storage implementation (TIER, which also uses eprd 
inside afaiu). I have not tested this stuff personally but seems very 
interesting.
In particular, latest published benchmarks of TIER against BCACHE at 
lessfs.com show TIER winning by a significant margin (about 2x). This 
stroke me because I read that bcache might be introduced into the kernel 
soon. Might TIER be a better choice?
Regards
S.
