Hi list,
It seems that the support for get_sb function is removed from kernel 2.6.39 onwards. My code which is working till 2.6.38 series is failing with new kernels.
The function "get_sb()" is still present in security/inode.c in kernel 2.6.39. Only the function pointer of get_sb() has been removed from
struct file_system_type in /include/linux/fs.h.
struct file_system_type in /include/linux/fs.h.
I tried finding out but there isnt anything mentioned. So if this function itself is removed then how kernel is going to find out the superblock and use it?
Are we supposed to use the mount function provided? This is what i got from one of the kernel patch email.
Yes , you are supposed to use mount function.

+[mandatory] + ->get_sb() is gone. Switch to use of ->mount(). Typically it's just +a matter of switching from calling get_sb_... to mount_... and changing the +function type. If you were doing it manually, just switch from setting ->mnt_root +to some pointer to returning that pointer. On errors return ERR_PTR(...). diff --git a/Documentation/filesystems/vfs.txt b/Documentation/filesystems/vfs.txt
It looks like there are other changes related to Pages are also done.
