| H A D | file.c | 3003bbd0 Thu Feb 06 08:22:29 CST 2020 David Howells <dhowells@redhat.com> afs: Use the netfs_write_begin() helper
Make AFS use the new netfs_write_begin() helper to do the pre-reading
required before the write. If successful, the helper returns with the
required page filled in and locked. It may read more than just one page,
expanding the read to meet cache granularity requirements as necessary.
Note: A more advanced version of this could be made that does
generic_perform_write() for a whole cache granule. This would make it
easier to avoid doing the download/read for the data to be overwritten.
