Should the VM_PFNMAP flag be cleared after a call to dma_mmap_coherent?

Hello, First, let me just say that this is more of a question rather than a proposal. I have a question regarding the behavior of the dma_mmap_coherent routine, and the VM_PFNMAP flag in general. Right now, it seems like the dma_mmap_coherent routine is essentially just a wrapper for remap_pfn_r

Hello, 4.19.45 doesn’t seem to build for me. I get an error on line 1231 of fs/open.c regarding a missing definition for “FMODE_STREAM”. I searched the entire tree for this definition and couldn’t find it defined anywhere. Thanks, Jake Moroni
