Signature of iommu_map changed in Rocky Linux 9.3 with kernel 5.14.0-362.8.1 #107
Description
Hello, in Rocky Linux 9.3 with kernel 5.14.0-362.8.1, I see that function iommu_map signature have changed.
[root@tcvrtdev08]# grep -A 2 "iommu_map(" /usr/src/kernels/5.14.0-362.8.1.el9_3.x86_64/include/linux/iommu.h
extern int iommu_map(struct iommu_domain *domain, unsigned long iova,
phys_addr_t paddr, size_t size, int prot, gfp_t gfp);
I tracked it down to following commit:

Following change in afhba_stream_drv.c fixes the compilation of AFHBA404, but I'm not sure what is it's effect. We can test the system and report back...
- if (iommu_map(adev->iommu_dom, iova, paddr, size, prot)){
+ if (iommu_map(adev->iommu_dom, iova, paddr, size, prot, GFP_KERNEL)){Here's the os and kernel version I'm using:
