nilfs-utils-2.2.7 Sun Nov 5, 2017 JST
* Fix conflicting data buffer error; this fixes a cleanerd crash
issue in some high loads that leads the file system to a disk
(obviously there has been tons of other fixes as well in releases since 2.2.2, as can be seen in the linked changelog)
I tested and confirmed that a simple cp is enough to bump, as expected.
Will bump to 2.2.8
