btrfs-progs: Accurate errormsg for resize operation on no-enouth-free-space case
btrfs progs output following error message when doing resize on
no-enouth-free-space case:
# btrfs filesystem resize +10g /mnt/btrfs_5gb
Resize '/mnt/btrfs_5gb' of '+10g'
ERROR: unable to resize '/mnt/btrfs_5gb' - File too large
#
It is not a good description for users, and this patch changed it to:
# ./btrfs filesystem resize +10G /mnt/tmp1
Resize '/mnt/tmp1' of '+10G'
ERROR: unable to resize '/mnt/tmp1' - no enouth free space
