Several tests uses both _filter_test_dir and _filter_scratch concatenated by pipe to filter $TEST_DIR and $SCRATCH_MNT. However, this would fail if the shorter string is a substring of the other (like "/mnt" and "/mnt2"). This patch introduces new common filter function to safely call both _filter_test_dir and _filter_scratch, and update tests and functions to use this new function. I checked this with btrfs/029, generic/409,410,411, and generic/381,383, xfs/106,108 (which calls _filter_quota). Thanks Eryu for advice.

# Check if creating a sparse copy ("reflink") of a file on btrfs
|
|
# expectedly fails when it's done between different filesystems or
|
|
# different mount points of the same filesystem.
|
|
#
|
|
# For both situations, these actions are executed:
|
|
# - Copy a file with the reflink=auto option.
|
|
# A normal copy should be created.
|
|
# - Copy a file with the reflink=always option. Should result in
|
|
# error.
