I found that the dirty flag will be used in the next few lines, so I keep
this function inside. If I move it outside, the drity flag should be passed
in as well.

@@ -774,6 +780,9 @@ static void *dax_insert_entry(struct xa_state *xas,
if (dirty)
xas_set_mark(xas, PAGECACHE_TAG_DIRTY);

+ if (cow)
+ xas_set_mark(xas, PAGECACHE_TAG_TOWRITE);
+
xas_unlock_irq(xas);
return entry;
}


So, may I ask what's your purpose for doing in that way?
