What happens to an IOCB_ATOMIC write to a zoned file? I think the
ioend for an atomic write to a zoned file involves a similar change as
an outofplace atomic write to a file (one big transaction to absorb
all the mapping changes) but I don't think the zoned code quite does
that...?
Correct. For now, I don't think that we should try to support zoned
device atomic writes. However we don't have proper checks for this. How
about adding a xfs_has_zoned() check in xfs_get_atomic_write_{min, max,
opt}()?
Thanks,
John
