Title:
zfs: upstream support for hardware-accelerated encryption
Status in linux package in Ubuntu:
Incomplete
Bug description:
I understand that in Linux 5.0+, certain encryption-related symbols
have been marked GPL-only, making them unavailable for use by zfs. As
a result, using encryption in zfs pools increases cpu load / decreases
disk throughput.
There are a pair of upstream pull requests that should improve the
performance (with performance measurement done on x86-64). Can these
be pulled into the Ubuntu kernel?
