Subject: [PATCH 00/21] RFC: Make all arches use <asm-generic/posix_types.h>
Date: Tue, 7 Feb 2012 21:08:44 -0800 [thread overview]
Message-ID: <1328677745-20121-1-git-send-email-hpa@zytor.com> (raw)
[Cc: list trimmed to avoid vger filters]
This patchset changes all architectures that don't already use
<asm-generic/posix_types.h> to do so. The purpose this threefold:
1. There is a dramatic amount of code removal.
2. New types can now be added in one place rather than having to go
through most of the architectures.
3. Removal of a bunch of old cruft.
The first two patches in the series tweak <asm-generic/posix_types.h>
to be more generally useful: the __kernel_[ug]id32_t types should
logically default to unsigned int instead of being mirrors of
__kernel_[ug]id_t, and the __kernel_fsid_t type is made overridable.
Patches 3-20 are patches for individual architectures; I would greatly
appreciate it if architecture maintainers would review their
respective architectures and verify that the transformation is
correct. These patches also remove the per-architecture fd_set
macros.
Patch 21, finally, removes the asm-generic version of the fd_set
macros. These macros were once upon a time exported to user space,
but that is now historic. Nowadays, they are nothing more than a
re-implementation of the bitops that we already have in the kernel, so
this final patch just replaces those with the appropriate standard
bitops.
