Hi list,<br>
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.<br>
<br></div></blockquote><div> </div><div> 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 <br>struct file_system_type in /include/linux/fs.h.<br>

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?<br>
<br>
Are we supposed to use the mount function provided? This is what i
got from one of the kernel patch email.<br>
<br></div></blockquote><div>Yes , you are supposed to use mount function.<br>visit the following link :<br><a href="http://lxr.linux.no/#linux+v2.6.39/security/inode.c%23L144" target="_blank">http://lxr.linux.no/#linux+v2.6.39/security/inode.c#L144</a><br>

+ ->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(...).
