Description Tomas Thiemel 2020-09-17 07:26:27 UTC 
I upgraded kernel from 5.7.13-gentoo to 5.7.19-gentoo.

I use "deduplication" daemon "bees":
[I] sys-fs/bees
     Available versions:  (~)0.6.1-r2 **9999*l {tools KERNEL="linux"}
     Installed versions:  0.6.1-r2(08:54:36 PM 12/17/2019)(-tools KERNEL="linux")
     Homepage:            https://github.com/Zygo/bees
     Description:         Best-Effort Extent-Same, a btrfs dedup agent
