liblitmus.git/src, branch 2011.1 [ARCHIVE] The userspace library for LITMUS^RT 2010. Now on GitHub. remove asm/atomic.h 2010-11-09T21:35:33+00:00 Bjoern B. Brandenburg bbb@cs.unc.edu 2010-11-06T23:26:02+00:00 5e40fcc568a204ce8b96f734a71402d0ca52e076 For historic resons, we carry old atomic operations support in liblitmus. This is no longer useful: 1) There is actually no client for these calls in liblitmus. 2) There is now a standard gcc API for this purpose. http://gcc.gnu.org/onlinedocs/gcc/Atomic-Builtins.html Thus, we can reduce our maintenance burden.

avoid including header files directly 2010-11-09T21:35:32+00:00 Bjoern B. Brandenburg bbb@cs.unc.edu 2010-11-06T20:20:13+00:00 42e747e4fe5648967c1ead5ae327b5fbbe66f2e5 The kernel warns against including header files directly. For good reason: our previous approach (just -I$KERNEL/include) caused all kinds of files to be included that should have come from /usr/include instead. This patch rewrites the Makfile so that the (few) needed headers are copied into the liblitmus src tree before compiling the library. This avoids having to specify the kernel include directories with -I, and also makes it easier to link against liblitmus (external applications do not need to know where the kernel is). Finally, this allows us to enable -Werror.

zero out rt_task parameters before setting them 2010-09-22T16:46:02+00:00 Bjoern B.

(Also, fix up some white space issues while we are at it.)
