Refactor the XFS error injection helpers to use the new errortag interface to configure error injection. If that isn't present, fall back either to the xfs_io/ioctl based injection or the older sysfs knobs. Refactor existing testcases to use the new helpers. Signed-off-by: Darrick J.

# FS QA Test No. 141
|
|
#
|
|
# Use the XFS log record CRC error injection mechanism to test torn writes to
|
|
# the log. The error injection mechanism writes an invalid CRC and shuts down
|
|
# the filesystem. The test verifies that a subsequent remount recovers the log
|
|
# and that the filesystem is consistent.
|
|
#
|
|
# Note that this test requires a DEBUG mode kernel.
