Hello,

I'm trying use your patch now, and I have a small comment in this document.

Probably, "-c" is necessary here.

xfs_io -c 'chattr +x' a


+mkdir a/b/c/d
+mkdir a/e
+
+ dax: a,e
+ no dax: b,c,d

+Example B:
+
+mkdir a
+xfs_io 'chattr +x' a
ditto
+mkdir -p a/b/c/d
+
+ dax: a,b,c,d
+ no dax:

+Example C:

+mkdir -p a/b/c
+xfs_io 'chattr +x' c
ditto
+mkdir a/b/c/d
