btrfs: tests, require fs_info for root

2016-07-26T11:53:18+00:00

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.

Btrfs: self-tests: Fix extent buffer bitmap test fail on BE system

2016-06-06T15:17:12+00:00

In __test_eb_bitmaps(), we write random data to a bitmap. Then copy
the bitmap to another bitmap that resides inside an extent buffer.
Later we verify the values of corresponding bits in the bitmap and the
bitmap inside the extent buffer. However, extent_buffer_test_bit()
reads in byte granularity while test_bit() reads in unsigned long
granularity. Hence we end up comparing wrong bits on big-endian
systems such as ppc64. This commit fixes the issue by reading the
bitmap in byte granularity.

Btrfs: self-tests: Fix test_bitmaps fail on 64k sectorsize

2016-06-06T15:17:12+00:00

With 64K sectorsize, 1G sized block group cannot span across bitmaps.
To execute test_bitmaps() function, this commit allocates
"BITS_PER_BITMAP * sectorsize + PAGE_SIZE" sized block group.

Btrfs: self-tests: Execute page straddling test only when nodesize < PAGE_SIZE

2016-06-06T15:17:11+00:00

On ppc64, PAGE_SIZE is 64k which is same as BTRFS_MAX_METADATA_BLOCKSIZE.
In such a scenario, we will never be able to have an extent buffer
containing more than one page. Hence in such cases this commit does not
execute the page straddling tests.

Btrfs: self-tests: Support non-4k page size

2016-06-02T17:23:14+00:00

self-tests code assumes 4k as the sectorsize and nodesize. This commit
fix hardcoded 4K. Enables the self-tests code to be executed on non-4k
page sized systems (e.g. ppc64).

Btrfs: Fix integer overflow when calculating bytes_per_bitmap

2016-06-02T17:22:49+00:00

On ppc64, bytes_per_bitmap will be (65536*8*65536). Hence append UL to
fix integer overflow.
