Hi All,
Is there a max number of slabs that can be used per kernel module? I'm having a tough time finding out that kind of information, but the array 'node_zonelists' (mmzone.h) has a size of 5. I just want to avoid buffer overruns and other bad stuff.
Cheers,

mount.ocfs2
mount.ocfs2(8) OCFS2 Manual Pages mount.ocfs2(8)
NAME
mount.ocfs2 - mount an OCFS2 filesystem
SYNOPSIS
mount.ocfs2 [-vn] [-o options] device dir
DESCRIPTION
mount.ocfs2 mounts an OCFS2 filesystem at dir. It is usually invoked indirectly by the mount(8) command when using the -t ocfs2 option.
OPTIONS
_netdev
The filesystem resides on a device that requires network access (used to prevent the system from attempting to mount these filesys-
tems until the network has been enabled on the system). mount.ocfs2 transparently appends this option during mount. However, users
mounting the volume via /etc/fstab must explicitly specify this mount option to delay the system from mounting the volume until
after the network has been enabled.
atime_quantum=nrsec
The file system will not update atime unless this number of seconds has passed since the last update. Set to zero to always update
atime. It defaults to 60 secs.
relatime
The file system only update atime if the previous atime is older than mtime or ctime.
noatime
The file system will not update access time.
acl / noacl
Enables / disables POSIX ACLs (Access Control Lists) support.
user_xattr / nouser_xattr
Enables / disables Extended User Attributes.
commit=nrsec
Sync all data and metadata every nrsec seconds. The default value is 5 seconds. Zero means default.
data=ordered / data=writeback
Specifies the handling of file data during metadata journalling.
ordered
This is the default mode. All data is forced directly out to the main file system prior to its metadata being committed
to the journal.
writeback
Data ordering is not preserved - data may be written into the main file system after its metadata has been committed to
the journal. This is rumored to be the highest-throughput option. While it guarantees internal file system integrity, it
can allow old data to appear in files after a crash and journal recovery.
datavolume
This mount option has been deprecated in OCFS2 1.6. It has been used in the past (OCFS2 1.2 and OCFS2 1.4), to force the Oracle
RDBMS to issue direct IOs to the hosted data files, control files, redo logs, archive logs, voting disk, cluster registry, etc. It
has been deprecated because it is no longer required. Oracle RDBMS users should instead use the init.ora parameter, filesys-
temio_options, to enable direct IOs.
errors=remount-ro / errors=panic
Define the behavior when an error is encountered. (Either remount the file system read-only, or panic and halt the system.) By
default, the file system is remounted read only.
localflocks
This disables cluster-aware flock(2).
intr / nointr
The default is intr that allows signals to interrupt cluster operations. nointr disables signals during cluster operations.
ro Mount the file system read-only.
rw Mount the file system read-write.
