hi !
I'm trying to patch kernel 2.4.20 with
htb 3.7.
Since I've source kernel at "/usr/src/linux"
and I've patch htb3.7 at "/usr/src/linux" too,
and patch file heads is:
--- /usr/src/linux-2.4/net/sched/sch_htb.c 2002/12/27 10:22:45
I put -p4 with patch command.
But patch fails:
[root@xxxxxx linux]# patch -p4 < htb_3.7_delay_bug.patch
patching file net/sched/sch_htb.c
Hunk #1 FAILED at 19.
1 out of 13 hunks FAILED -- saving rejects to file net/sched/sch_htb.c.rej
Could someone help me ?
Thank you in advance !
Mac
... ThE PhP_KiD.
