ext4: add debugging trigger for ext4_error()
Make it easy to test whether or not the error handling subsystem in ext4 is working correctly. This allows us to simulate an ext4_error() by echoing a string to /sys/fs/ext4/<dev>/trigger_fs_error. Signed-off-by: "Theodore Ts'o" <tytso@mit.edu> Cc: ksumrall@google.com
