Subject: [PATCH v4 02/26] fs: proc: Delete inode time initializations in proc_alloc_inode()
Date: Sat, 13 Aug 2016 15:48:14 -0700	[thread overview]
Message-ID: <1471128518-24075-3-git-send-email-deepa.kernel@gmail.com> (raw)
In-Reply-To: <1471128518-24075-1-git-send-email-deepa.kernel@gmail.com>

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().
