Subject: IB/rdmavt: Don't vfree a kzalloc'ed memory region
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=e4618d40eb3dc1a6d1f55f7150ea25bb23ab410a;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

IB/rdmavt: Don't vfree a kzalloc'ed memory region

The userspace memory region 'mr' is allocated with kzalloc in
__rvt_alloc_mr  however it is incorrectly being freed with vfree in
__rvt_free_mr. Fix this by using kfree to free it.
