The following list of LTP syscalls failure noticed on qemu-arm64 with
stable-rc 6.16.1-rc1 with CONFIG_ARM64_64K_PAGES=y build configuration.

Most failures report ENOSPC (28) or mkswap errors, which may be related
to disk space handling in the 64K page configuration on qemu-arm64.

The issue is reproducible on multiple runs.

I'm also seeing epoll_ctl04 failing on Raspberry Pi 4, there's a bisect
still running but I suspect given the error message:

epoll_ctl04.c:59: TFAIL: epoll_ctl(..., EPOLL_CTL_ADD, ...) with number of nesting is 5 expected EINVAL: ELOOP (40)

that it might be:

# bad: [b47ce23d38c737a2f84af2b18c5e6b6e09e4932d] eventpoll: Fix semi-unbounded recursion

which already got tested, or something adjacent.
