2.2.0-pre[1-9] breaks libc-5.4.46 compiles
When compiling the kernel...
mm.h includes sched.h sched.h includes binfmts.h binfmts.h includes fs.h #if defined __KERNEL__ fs.h includes affs_fs_i.h affs_fs_i.h includes time.h time.h defines struct timeval and... sched.h includes timex.h /* Starting with 2.2.0-pre1 */ timex.h uses struct timeval /* OK because in the kernel */ /* time.h was included */ so everything is fine...
When compiling libc-5.4.46...
__fpathconf.c includes sched.h sched.h includes binfmts.h binfmts.h includes fs.h and... sched.h includes timex.h /* Starting with 2.2.0-pre1 */ timex.h uses struct timeval /* Not OK because in libc */ /* time.h is not included */
Basically timex.h will not compile unless time.h has already been included.
Should the kernel headers be idempotent? i.e. should I be able to write
========================= xxq.c begin #include <linux/some-arbitrary-header.h> ========================= xxq.c end
and compile it?
