xfsprogs prior to commit 2f9a125c3a39 ("xfsprogs: replace
pread64/pwrite64 by equivalent pread/pwrite") will see "pwrite64:
Text file busy" error. Just filter these "pwrite64"s to "pwrite"
with _filter_xfs_io_error.

While active, the media backing a swap file is leased to the kernel.
Userspace has no business writing to it. Make sure we can't do this.
The two kernel patches titled as below should fix the bug:
mm: set S_SWAPFILE on blockdev swap devices
vfs: don't allow writes to swap files
