Subject: RDMA/mlx5: Pass UMR segment flags instead of boolean
X-Git-Tag: v5.15~5930^2~100
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=9ac7c4bcd383adbac9ad02ec033cce9a3a261d28;p=platform%2Fkernel%2Flinux-starfive.git

RDMA/mlx5: Pass UMR segment flags instead of boolean

UMR ctrl segment flags can vary between UMR operations. for example,
using inline UMR or adding free/not-free checks for a memory key.
This is a preparation commit before adding new signature API that
will not need not-free checks for the internal memory key during the
UMR operation.
