Hi all,
Is there anybody know how to invoke the "discard" operation over btrfs
filesystem? Does delete a file by "rm" will trigger the "discard"
operation?
If I want to trigger "discard" operation,how should i do? if there any
pre-requires? such as the device must be ssd, btrfs should be mounted
with "-o discard".
Any suggestion is appreciated.
Thanks a lot!
