Title:
backport btrfs ssd mount option fix
Status in linux package in Ubuntu:
Triaged
Bug description:
Hello,
It appears that all kernels before 4.14 had a problem with btrfs ssd
mount option. According to
https://btrfs.wiki.kernel.org/index.php/Gotchas#ssd_mount_option, it
has a negative impact on usability and lifetime of modern SSDs. Since
it is enabled by default when SSD is detected, it affects all systems
with SSD drives. Please backport this commit to normal and HWE
kernels:
