Public bug reported: SRU Justification: (Trusty)
[Impact] Illegal and/or incorrect btrfs resize parameters can be passed to the btrfs_ioctl_resize handler and it is not picked up as an error. [Fix] upstream commit 9a40f1222a372de77344d85d31f8fe0e1c0e60e7 "btrfs: filter invalid arg for btrfs resize" this is a simple parsing check, risk is low to zero. [Testcase] # btrfs fi resize -10A <mnt> # btrfs fi resize -10Gaha <mnt> These should fail with -EINVAL. Without the fix, they don't.
