btrfs: tests: uninline member definitions in free_space_extent

2016-10-03T16:52:15+00:00

The recommended way is to put all members on separate lines.

btrfs: tests: constify free space extent specs

2016-10-03T16:52:15+00:00

We don't change the given extent ranges, mark them const to catch
accidental changes.

Btrfs: expand free space tree sanity tests to catch endianness bug

2016-10-03T16:52:14+00:00

The free space tree format conversion functions were broken on
big-endian systems, but the sanity tests didn't catch it because all of
the operations were aligned to multiple words. This was meant to catch
any bugs in the extent buffer code's handling of high memory, but it
ended up hiding the endianness bug. Expand the tests to do both
sector-aligned and page-aligned operations.

Btrfs: fix extent buffer bitmap tests on big-endian systems

2016-10-03T16:52:14+00:00

The in-memory bitmap code manipulates words and is therefore sensitive
to endianness, while the extent buffer bitmap code addresses bytes and
is byte-order agnostic. Because the byte addressing of the extent buffer
bitmaps is equivalent to a little-endian in-memory bitmap, the extent
buffer bitmap tests fail on big-endian systems.

34b3e6c92af1 ("Btrfs: self-tests: Fix extent buffer bitmap test fail on
BE system") worked around another endianness bug in the tests but missed
this one because ed9e4afdb055 ("Btrfs: self-tests: Execute page
straddling test only when nodesize < PAGE_SIZE") disables this part of
the test on ppc64. That change lost the original meaning of the test,
however. We really want to test that an equivalent series of operations
using the in-memory bitmap API and the extent buffer bitmap API produces
equivalent results.

To fix this, don't use memcmp_extent_buffer() or write_extent_buffer();
do everything bit-by-bit.

Btrfs: add a flags field to btrfs_fs_info

2016-09-26T15:59:49+00:00

We have a lot of random ints in btrfs_fs_info that can be put into flags.  This
is mostly equivalent with the exception of how we deal with quota going on or
off, now instead we set a flag when we are turning it on or off and deal with
that appropriately, rather than just having a pending state that the current
quota_enabled gets set to.  Thanks,

btrfs: extend btrfs_set_extent_delalloc and its friends to support in-band dedupe and subpage size patchset

2016-09-26T15:59:49+00:00

Extend btrfs_set_extent_delalloc() and extent_clear_unlock_delalloc()
parameters for both in-band dedupe and subpage sector size patchset.

This should reduce conflict of both patchset and the effort to rebase
them.

btrfs: tests, require fs_info for root

This allows the upcoming patchset to push nodesize and sectorsize into
fs_info.

btrfs: tests, move initialization into tests/

2016-07-26T11:53:17+00:00

We have all these stubs that only exist because they're called from
btrfs_run_sanity_tests, which is a static inside super.c.  Let's just
move it all into tests/btrfs-tests.c and only have one stub.

Btrfs: fix error return code in btrfs_init_test_fs()

2016-06-23T17:44:39+00:00

Fix to return a negative error code from the kern_mount() error handling
case instead of 0(ret is set to 0 by register_filesystem), as done
elsewhere in this function.
