To: fstests, linux-btrfs
Various tests have more or less copy and pasted code to enable and
disable block layer "fail make request" error injection. Move that
to a set of common helpers and use those in the drivers.
btrfs/150 differened from the other two in a few ways, like selecting
a not quite as big number to fail all requests in the small critical
section and clearing a bunch of never set attributes in the failure
injection configuration, but none of those matter for the test
execution.

Test that a write with a single bad mirror works fine but reports errors
in the error counters, and that a write with two bad mirrors fails.

Hm. more below.

Instead, can we do
printf %#x -1 > $DEBUGFS_MNT/fail_make_request/times
(as in the documentation).

Only extra line in btrfs/150 is the above line (or did I miss any)?
Which is deleted in this patch.
Per 'task-filter' documentation
--------------
- /sys/kernel/debug/fail*/task-filter:
Format: { 'Y' | 'N' }
A value of 'N' disables filtering by process (default).
Any positive value limits failures to only processes indicated by
/proc/<pid>/make-it-fail==1.

So this won't work now.
