[LEDE-DEV] NFS force/lazy umount

[Denis Periša]

Sorry to bother you all but this problem is frustrating for too long
time (years)

I have NFS server which might become unreachable;
during that time all my access to LEDE firmware is limited (ls, df,
scp).. and umount -f and umount -l don't do anyhing. Could as well be
removed.

I know about soft mount.

can someone find problem? I'm not much of a coder.

thank you!
