Subject[PATCH] Fix a bad bug in read_cache_page_async()
Date
Fix a bad bug in read_cache_page_async() introduced in commit:

6fe6900e1e5b6fa9e5c59aa5061f244fe3f467e2

This adds:

mark_page_accessed(page)

into the error handling path in read_cache_page_async(). In such a case,
'page' holds the error code.
