David Howells 881aee27ce mm: Fix missing folio invalidation calls during truncation
[ Upstream commit 0aa2e1b2fb7a75aa4b5b4347055ccfea6f091769 ]

When AS_RELEASE_ALWAYS is set on a mapping, the ->release_folio() and
->invalidate_folio() calls should be invoked even if PG_private and
PG_private_2 aren't set.  This is used by netfslib to keep track of the
point above which reads can be skipped in favour of just zeroing pagecache
locally.

There are a couple of places in truncation in which invalidation is only
called when folio_has_private() is true.  Fix these to check
folio_needs_release() instead.

Without this, the generic/075 and generic/112 xfstests (both fsx-based
tests) fail with minimum folio size patches applied[1].

Fixes: b4fa966f03 ("mm, netfs, fscache: stop read optimisation when folio removed from pagecache")
