Extend _require_xfs_io_command so that we can pass it a command line argument to look for, and then use new capabililty in the relevant tests to ensure that bmap knows how to dump CoW fork contents (bmap -c) Signed-off-by: Darrick J.

# Make sure that reflink deals with extents going beyond EOF.

|
# - fallocate 256k in file1
|
|
# - pwrite 252-257k to cause it to speculatively prealloc file1

# - reflink file1 to file2
