[$] Filesystem support block sizes larger than the page size

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