Subject: [PATCH] mkfs.xfs: allow specification of 0 data stripe width & unit
|
|
|
|
|
|
|
|
|
|
The "noalign" option works for this too, but it seems reasonable
|
|
|
|
|
to allow explicit specification of stripe unit and stripe width
|
|
|
|
|
to 0; today, doing so today makes the code think it's unspecified,
|
|
|
|
|
and so it goes ahead and detects stripe geometry and sets it in the
|
|
|
|
|
superblock. That's unexpected and surprising.
|
|
|
|
|
|
|
|
|
|
Create a new flag that tracks whtether a geometry option has been
|
|
|
|
|
specified, and if it's set along with 0 values, treat it the
|
|
|
|
|
same as if "noalign" had been specified.
