Subject: [PATCH 6/7] vdo: fix input units for minimim_io_size
|
|
|
|
When specifying minimum_io_size with --vdosettings,
|
|
command assumed wrong unit (sectors).
|
|
|
|
So '--vdosettings minimum_io_size=512|4096' resulted into
|
|
an error that only 512 or 4096 values are allowed, but
|
|
at the same time values 1 or 8 were accepted.
|
|
|
|
So fix by converting any number >= 512 to 'sectors' and
|
|
keep input of 1 or 8 still valid if anyone has been using
|
|
this before.
|
|
|
|
So now we take 512 or 4096 and still also 1 or 8 with the
|
|
same effect.
|
|
|
|
Also correct the 'error' message when invalid minimum_io_size
|
|
is specified.
|
|
|
|
(cherry picked from commit 158d3243b638f50f62c60128168c21840787f1ab)
