[PATCH] uml: use fork instead of clone

2005-06-14T03:58:43+00:00

Convert the boot-time host ptrace testing from clone to fork.  They were
essentially doing fork anyway.  This cleans up the code a bit, and makes
valgrind a bit happier about grinding it.

[PATCH] uml: fix strace -f

2005-06-08T23:21:12+00:00

It turns out that we need to check for pending signals when a newly forked
process is run for the first time.  With strace -f, strace needs to know about
the forked process before it gets going.  If it doesn't, then it ptraces some
bogus values into its registers, and the process segfaults.  So, I added calls
to interrupt_end, which does that, plus checks for reschedules.  There
shouldn't be any of those, but x86 does the same thing, so I'm copying that
behavior to be safe.

[PATCH] uml: remove jail mode + other leftovers

2005-05-28T23:46:14+00:00

This var is currently useless, as it's apparent from reading the code. Until
2.6.11 it was used in some code related to jail mode, in the same proc.:

        if(jail){
		while(!reading) sched_yield();
	}

jail mode has been dropped, together with that use, so let's finish dropping
this.

Also, remove some other useless definitions I met.

2005-05-28T23:46:11+00:00

Remove old useless header that was used in Ye Olde Times during 2.4->2.5
porting to abstract differences.  It's definitions are no more used anyway, so
let's finally kill it.
