linux-toradex.git/fs/ext4/hash.c, branch v3.0.44 Linux kernel for Apalis and Colibri modules ext4: Add support for non-native signed/unsigned htree hash algorithms 2008-10-28T17:21:44+00:00 Theodore Ts'o tytso@mit.edu 2008-10-28T17:21:44+00:00 f99b25897a86fcfff9140396a97261ae65fed872 The original ext3 hash algorithms assumed that variables of type char were signed, as God and K&R intended. Unfortunately, this assumption is not true on some architectures. Userspace support for marking filesystems with non-native signed/unsigned chars was added two years ago, but the kernel-side support was never added (until now).

[PATCH] remove many unneeded #includes of sched.h 2007-02-14T16:09:54+00:00 Tim Schmielau tim@physik3.uni-rostock.de 2007-02-14T08:33:14+00:00 cd354f1ae75e6466a7e31b727faede57a1f89ca5 After Al Viro (finally) succeeded in removing the sched.h #include in module.h recently, it makes sense again to remove other superfluous sched.h includes. There are quite a lot of files which include it but don't actually need anything defined in there. Presumably these includes were once needed for macros that used to live in sched.h, but moved to other header files in the course of cleaning it up. To ease the pain, this time I did not fiddle with any header files and only removed #includes from .c-files, which tend to cause less trouble. Compile tested against 2.6.20-rc2 and 2.6.20-rc2-mm2 (with offsets) on alpha, arm, i386, ia64, mips, powerpc, and x86_64 with allnoconfig, defconfig, allmodconfig, and allyesconfig as well as a few randconfigs on x86_64 and all configs in arch/arm/configs on arm. I also checked that no new warnings were introduced by the patch (actually, some warnings are removed that were emitted by unnecessarily included header files).
