Transpire global --verbose and --quiet options down to the btrfs send sub-command. Suggested-by: David Sterba <dsterba@suse.com> Signed-off-by: Anand Jain <anand.jain@oracle.com> --- Global verbose-and-quiet option sequences behave differently from the same sequence used in the local command, as show below. Before: btrfs.old send -q -v -f /tmp/f -p /btrfs/ss2 /btrfs/ss3 At subvol /btrfs/ss3 btrfs.old send -v -f /tmp/f -p /btrfs/ss2 /btrfs/ss3 At subvol /btrfs/ss3 BTRFS_IOC_SEND returned 0 joining genl thread After: btrfs.new send -q -v -f /tmp/f -p /btrfs/ss2 /btrfs/ss3 At subvol /btrfs/ss3 btrfs.new -q -v send -f /tmp/f -p /btrfs/ss2 /btrfs/ss3 At subvol /btrfs/ss3 BTRFS_IOC_SEND returned 0 joining genl thread The (btrfs.new -q -v send) output is same as (btrfs.old send -v) which IMO is acceptable and not a regression. cmds/send.c | 33 +++++++++++++++++++++------------ 1 file changed, 21 insertions(+), 12 deletions(-)
