Problem with this once as well:
$ patch --dry-run -p1 < ../11_08_2008-\([EMAIL PROTECTED]
\)-003_message_queue_test05.patch
missing header for unified diff at line 175 of patch
can't find file to patch at input line 175
Perhaps you used the wrong -p or --strip option?
The text leading up to this was:
--------------------------
.........................
.......................
--------------------------
File to patch: testcases/kernel/ipc/ipc_stress/message_queue_test_05.c
patching file testcases/kernel/ipc/ipc_stress/message_queue_test_05.c
patch: **** malformed patch at line 182: IPC_RMID, 0);
Can you please resend this as well ?
Regards--
