log-structured caching for Linux
dm-writeboost is an OS-level IO controller that builds logs from in-coming writes (data and metadata) and then writes the logs sequentially similar to log-structured filesystem. As a further extension, dm-writeboost supports read-caching which also writes data sequentially. . This package provides DKMS kernel module for Linux Kernel 3.10+.
