Subject: [PATCH 16/43] block-backend: align max_transfer to request alignment
|
|
|
|
RH-Author: Miroslav Rezanina <mrezanin@redhat.com>
|
|
RH-Bugzilla: 1957194
|
|
|
|
Block device requests must be aligned to bs->bl.request_alignment.
|
|
It makes sense for drivers to align bs->bl.max_transfer the same
|
|
way; however when there is no specified limit, blk_get_max_transfer
|
|
just returns INT_MAX. Since the contract of the function does not
|
|
specify that INT_MAX means "no maximum", just align the outcome
|
|
of the function (whether INT_MAX or bs->bl.max_transfer) before
|
|
returning it.
