Konstantin Belousov b6c00483e9 Do not leave invalid pages in the object after the short read for a ... network file systems (not only NFS proper). Short reads cause pages other then the requested one, which were not filled by read response, to stay invalid. Change the vm_page_readahead_finish() interface to not take the error code, but instead to make a decision to free or to (de)activate the page only by its validity. As result, not requested invalid pages are freed even if the read RPC indicated success. Noted and reviewed by: alc MFC after: 1 week		2012-08-14 11:45:47 +00:00
