When using the NO_HOLES feature, if we clone a file range that spans only
a hole into a range that is at or beyond the current i_size of the

clone a file range covering only a hole into an offset beyond the current

Hi,
this update brings updates of space handling, performance improvements
or bug fixes. The subpage block size and zoned mode features have
reached state where they're usable but with limitations.

Old code made a failure in fstest btrfs/006.

I'm worried about this patch makes other problem. So make it RFC. Thanks.

Hi,
Thank you. If I have to clone, I think I'll just get rid of the

Thanks. Unfortunately, this machine with this file system can boot
only with 3.10 kernel somehow. Now it is started, and I hope it can
hold the line while I'm creating another machine with a different FS.

The tree checker checks the extent ref hash at read and write time to
make sure we do not corrupt the file system. Generally extent
references go inline, but if we have enough of them we need to make an
item, which looks like
key.objectid=
key.type=
key.offset = hash(tree, owne
This is a regression test for a problem where we would flip read only if
we reflink'ed enough extents to generate key'ed references, and then got
a hash collision with those references. This is a test for the fix
btrfs: do not error out if the extent ref hash doesn't match
and is relativ

The problem is we're copying "inherit" from user space but we don't
necessarily know that we're copying enough data for a 64 byte
