The fault handling routines really want more fine-grained flags than a single "was it a write fault" boolean - the callers will want to set flags like "you can return a retry error" etc. And that's actually how the VM works internally, but right now the top-level fault handling functions in mm/memory.c all pass just the 'write_access' boolean around. This switches them over to pass around the FAULT_FLAG_xyzzy 'flags' variable instead. The 'write_access' calling convention still exists for the exported 'handle_mm_fault()' function, but that is next. Signed-off-by: NLinus Torvalds <torvalds@linux-foundation.org>
