Subject: [LTP] [PATCH] drop redudant copies of fsx-linux.c
From: Daniel Gollub <dgollub () suse ! de>
Date: 2008-10-30 10:05:36
Message-ID: 200810301105.36910.dgollub () suse ! de
[Download RAW message or body]
Hi,
this patch drops the redudant copies (in total three copies of fsx-linux.c
from:
- testcases/kernel/io/ltp-aiodio/
- testcases/network/nfs/fsx-linux
The only copy of fsx-linux.c will stay in:
- testcases/kernel/fs/fsx-linux/fsx-linux.c
Attachted patch adapt the TCbin= variable of the runtests file to the install target
"$LTPROOT/testcases/bin" to find the (shared) build of fsx-linux.
Signed-off-by: Daniel Gollub <dgollub@suse.de>
