ceph: convert ceph_fill_inline_data() to take a folio

Browse source

Convert the internals to folio APIs and pass a folio in from
ceph_fill_inode(). The kmap_atomic()/memcpy() pair becomes
memcpy_to_folio(), which also flushes the dcache, so drop the explicit
flush from the folio creation path. When a locked folio is passed in,
the callers flush after filling it, so the flush in memcpy_to_folio()
is redundant there, but harmless.

This removes the last caller of find_or_create_page() in ceph and saves
six calls to compound_head(). The page_folio() call added in
ceph_fill_inode() goes away once the locked page plumbing is converted.

Remove extern from the function declaration while at it.
