Display mount table

sajanagr · 09-08-2010, 01:24 AM

Hi friends
I am looking to display the mount table of my system using printk.
But I am not able to find the right method.

I am exploring fs/namespace.c file and explored it and came across lookup_mnt function.
I know that a global list is maintained to store the descriptors of the mounted filesystems( vfsmount ), and I am in the process to track and display it.

Any pointers will also be helpful.

Thanks in advance.

open a terminal

#mount -l (-l is small character L)

Hi
Thanks for replying but I am looking to print the mount table from the list at kernel space.

you could try using the proc file system /proc/mounts

Yeah I agree with bsat.

Hi thanks for reply. I think the implementation is similar to displayed by /proc/mounts

Can you tell me what data structure the mount table is stored in (the name of structure) ? and what kind of strucutre it is ?

I am not sure but you can see in linux/mount.h it might help.
