[PATCH v7 6/6] dax: fix a comment in dax_zero_page_range and dax_truncate_page
From: Vishal Verma <vishal.l.verma@intel.com>
Date: 2016-05-11 21:08:52
Also in:
linux-block, linux-fsdevel, linux-mm, linux-xfs, lkml, nvdimm
Subsystem:
filesystem direct access (dax), filesystems (vfs and infrastructure), the rest · Maintainers:
Dan Williams, Alexander Viro, Christian Brauner, Linus Torvalds
The distinction between PAGE_SIZE and PAGE_CACHE_SIZE was removed in
09cbfea mm, fs: get rid of PAGE_CACHE_* and page_cache_{get,release}
macros
The comments for the above functions described a distinction between
those, that is now redundant, so remove those paragraphs
