proc uses new_inode_pseudo() to allocate a new inode. This in turn calls the proc_inode_alloc() callback. But, at this point, inode is still not initialized with the super_block pointer which only happens just before alloc_inode() returns after the call to inode_init_always().
Also, the inode times are initialized again after the call to new_inode_pseudo() in proc_inode_alloc(). The assignemet in proc_alloc_inode() is redundant and also doesn't work after the current_time() api is changed to take struct inode* instead of struct *super_block.
This bug was reported after current_time() was used to assign times in proc_alloc_inode().
