So I am thinking one of these:
a. stx_atomic_write_unit_max_dev
b. stx_atomic_write_unit_max_bdev
c. stx_atomic_write_unit_max_align
d. stx_atomic_write_unit_max_hw
The terms dev (or device) and bdev are already used in the meaning of some
members in struct statx, so not too bad. However, when we support large
atomic writes for XFS rtvol, the bdev atomic write limit and rtextsize
would influence this value (so just bdev might be a bit misleading in the
name).
Don't. Especially when you have a natively out of write file system
that optimized case will not involve the usual hardware offload.
stx_atomic_write_unit_max_opt it is then.
Or stx_atomic_write_unit_max_optimal or stx_atomic_write_unit_max_fast.
Or similar..
cheers,
