Hi,
Is there a exported routine, which I can use in my kernel module
to get the file system type name. Just like I use sysfs(GETFSTYP,...)
in the userspace application code, and get the filesystem type name as
vxfs or ufs/hfs or nfs etc.

Thanks

Hello

In the kernel there is no such interface available it seems. You have
to get the vnode of the file system mount path using lookupname() and
take the vfstype - it is an enum. The definition of vfstype is
available in the vnode.h. Please check.

The lookupname returns 2 vnodes
After getting the type info you want release the vnodes.

hth,
regards,
vasanth.

Well I probably want this information for any file system which is not
already mounted. Ok, have got a similar question How do I get vfsops
information for a given file system. Again better if I can get this
information irrespective of mounted or not.

Thanks.
