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>

<div>The name they have kept is the same in security/inode.c but you can compare the prototype to earlier kernel versions. They will be different. Also its assigned to mount function pointer field of struct file_system_type. <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><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
