btrfs: tests: add separate stub for find_lock_delalloc_range

2018-10-15T15:23:34+00:00

The helper find_lock_delalloc_range is now conditionally built static,
dpending on whether the self-tests are enabled or not. There's a macro
that is supposed to hide the export, used only once. To discourage
further use, drop it an add a public wrapper for the helper needed by
tests.

Btrfs: extent_map: use rb_first_cached

2018-10-15T15:23:33+00:00

rb_first_cached() trades an extra pointer "leftmost" for doing the
same job as rb_first() but in O(1).

As evict_inode_truncate_pages() removes all extent mapping by always
looking for the first rb entry, it's helpful to use rb_first_cached
instead.

For more details about the optimization see patch "Btrfs: delayed-refs:
use rb_first_cached for href_root".

btrfs: tests: drop newline from test_msg strings

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)

btrfs: Remove fs_info argument from __remove_from_free_space_tree

2018-05-28T16:07:35+00:00

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