The maximum filesystem block size that the kernel can support has always
been limited by the host page size for Linux, even if the filesystems could
handle larger block sizes. The large-block-size (LBS) patches that were merged
for the 6.12 kernel removed this limitation in XFS, thereby decoupling
the page size from the filesystem block size. XFS is the first filesystem
to gain this support, with other filesystems likely to add LBS support in
the future. In addition, the LBS patches have been used to get the initial atomic-write support into XFS.
