Hi there
running fstrim on a F2FS partition gives the following output:
fstrim: /home: discard operation not supported.
kernel 3.16.0-rc2
Is this normal?
Cheers
Brian

Now f2fs has not yet supported batch mode discard through ioctl as the way
fstrim used.
Still you could use real-time mode discard by adding a '-o discard' option when
mount, meanwhile /sys/fs/f2fs/<devname>/max_small_discards could be used for
controlling the real-time mode.
Thanks
Yu

Exactly, it's correct.
Thanks Chao, :)
