Oh, and I had a xfs pull request in my inbox already, so rather than
expect Darrick to do another one just for this and have Jan do one for
ext2, I just applied these two directly as "ObviouslyCorrect(tm)".
I added the "inline" as suggested by Darrick, and I also added
parenthesis around the bit tests.
Yes, I know the C precedence rules, but I just personally find the
code easier to read if I don't even have to think about it and the
different subexpressions of a logical operation are just visually very
clear. And as I was editing the patch anyway...
So that xfs helper function now looks like this
+static inline bool
+xfs_is_write_fault(
+ struct vm_fault *vmf)
+{
+ return (vmf->flags & FAULT_FLAG_WRITE) &&
+ (vmf->vma->vm_flags & VM_SHARED);
+}
instead.
