btrfs: tests: drop newline from test_msg strings

2018-05-29T16:12:52+00:00

Now that test_err strings do not need the newline, remove them also from
the test_msg.

btrfs: tests: add helper for error messages and update them

2018-05-29T16:12:51+00:00

The test failures are not clearly visible in the system log as they're
printed at INFO level. Add a new helper that is level ERROR. As this
touches almost all strings, I took the opportunity to unify them:

- decapitalize the first letter as there's a prefix and the text
  continues after ":"
- glue strings split to more lines and un-indent so they fit to 80
  columns
- use %llu instead of %Lu
- drop \n from the modified messages (test_msg is left untouched)

This function takes a transaction handle which holds a reference to
fs_info. So use that and remove the extra argument.

btrfs: use fs_info for btrfs_handle_em_exist tracepoint

2018-05-28T16:07:17+00:00

We really want to know to which filesystem the extent map events belong,
but as it cannot be reached from the extent_map pointers, we need to
pass it down the callchain.
