Rebased to current Linus' tree -- c05c2ec96bb8.
The first patch was regenerated with coccinelle, the rest just re-applied
on top.
]
PAGE_CACHE_{SIZE,SHIFT,MASK,ALIGN} macros were introduced *long* time ago
with promise that one day it will be possible to implement page cache with
bigger chunks than PAGE_SIZE.
This promise never materialized. And unlikely will.
We have many places where PAGE_CACHE_SIZE assumed to be equal to
PAGE_SIZE. And it's constant source of confusion on whether PAGE_CACHE_*
or PAGE_* constant should be used in a particular case, especially on the
border between fs and mm.
Global switching to PAGE_CACHE_SIZE != PAGE_SIZE would cause to much
breakage to be doable.
Let's stop pretending that pages in page cache are special. They are not.
The changes are pretty straight-forward:
- <foo> << (PAGE_CACHE_SHIFT - PAGE_SHIFT) -> <foo>;
- <foo> >> (PAGE_CACHE_SHIFT - PAGE_SHIFT) -> <foo>;
- PAGE_CACHE_{SIZE,SHIFT,MASK,ALIGN} -> PAGE_{SIZE,SHIFT,MASK,ALIGN};
- page_cache_get() -> get_page();
- page_cache_release() -> put_page();
The first patches with most changes has been done with coccinelle.
The second is manual fixups on top.
The third patch which removes macros definition can be postponed to allow more
gradual transition.
Please, consider applying.
Kirill A. Shutemov (3):
mm, fs: get rid of PAGE_CACHE_* and page_cache_{get,release} macros
mm, fs: remove remaining PAGE_CACHE_* and page_cache_{get,release}
usage
mm: drop PAGE_CACHE_* and page_cache_{get,release} definition
