LTP syscalls swapon01, swapon02, swapon03, swapoff01 and swapoff02 test failing
on 16K and 64K page arm64 devices and passed with default 4K page size.

These failures are noticed on Linux next and mainline master (v6.17).

This test failed on 16K page size builds and 64K page size builds.

[now that this has come up twice I'm replying]

Yikes, you can do swap over FUSE?  Ohhhh, that's why fuse implements
bmap in the aops.

The last I heard from Joanne, the workaround in that bd24d2108 commit
will go away when she lands iomap for read{,ahead} in 6.19.  Not sure
what the solution is in the meantime.

I speculate that the problem here is that the superblock
s_blocksize_bits always gets reset to PAGE_SHIFT even if the fuse server
had set another value, and now there's a mismatch and the swapfile code
rejects?

<shrug> I dunno how much people care about swap over fuse, but it /is/ a
breaking change.
