[I repost this patch because in the previous attempt I forgot
the comment]
Hi All,
the enclosed patch adds tests to the xfstest suite to check the
btrfs allocation_hint property.
Each test creates file and fills the different disks, up to
trigger a new BG data (or metadata) allocation. Then the
test checks if the allocation if the new BG is perfomed
in the new disk.
Because we need to fill an entire disk, the tests are performed
on some device-mapper slices of $SCRATCH_DEV. The slices have
a length of 1GB (512MB for test 269/270)
This is my first xfstest patches, so I expected to do a lot
of error :-); a deeply review is appreciated.
Test 269 and 270 are quite long (about 5-8 minutes on my virtual
machine with sync disabled). This because I need to fill a 512MB
disk of metadata. The only way to do that is to fill the disk with
a lot of 2k size files. This is very slow. If someone has a better
way to do that, it is very appreciated.
I added a V12 tag because the allocation_hint patch set is in
the 12th revision.
Changelog:
- V12:
Rebase to the latest version of xfstest suite (renamed the tests from
255...264 to 262..271)
- V10:
First issue
