Subject: [PATCH 0/2] btrfs: enable full bs <= ps support
Date: Fri, 19 Jun 2026 18:24:45 +0930	[thread overview]
Message-ID: <cover.1781859111.git.wqu@suse.com> (raw)

Btrfs has supported block size < page size for a while, but that is only
when the block size is 4K.
So for 64K page size, 8K/16K/32K block sizes are not supported no matter
what.

That's is completely an artificial limit, introduced just to reduce our
test workload.
But after all these years, we even have experimental bs > ps support
now.

There is really no reason not to support the extra block sizes.

The first patch is a small comment update.
The second one introduces the real change.

Qu Wenruo (2):
  btrfs: remove the out-of-date comments on the 2K block size
  btrfs: allow any block size that is no larger than page size
