I am sorry about the format of my messages. I have modified it, but it does not seem to take. If you still cannot see this message well again, I will switch to a different mail app.
To clarify things: Rhel 6.1 kernel 2.6.32-131.21 with aufs2-standalone.tree-32-20100621 in which the mount.aufs is a shell script <- works well Rhel 6.2 kernel 2.6.32-220.13 with aufs2-standalone.tree-32-20100621 kernel panics at the mount.aufs command RIP statfs_by_dentry Rhel 6.3 kernel 2.6.32-279 with aufs2.1-standalone.tree-32-20110801 fails on the open(/dev/tty) as indicated in the strace The C runtime environment is the same on all. Mount.aufs is statically linked for Rhel 6.3. I am wondering if the problem has to do with the error I received when I tried using a different compiler when building the rhel 6.3 kernel: ccl:warnings being treated as errors fs/aufs/super.c: In function au_statfs_sum fs/aufs/super.c:325: error: passing argument 1 of vfs_statfs from incompatible pointer type include/linux/fs.h:1867: note: expected struct path * but argument is of type struct dentry * This same error is also in super.c function aufs.statfs. This is the fs.h header file: Rhel 6.1 kernel: linux/include/linux/fs.h:extern int vfs_statfs(struct dentry *, struct kstatfs *); Rhel 6.3 kernel: linux/include/linux/fs.h:extern int vfs_statfs(struct path *, struct kstatfs *); ------------------------------------------------------------------------------ Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.
