The patch titled
vfs: kill->put_inode
has been removed from the -mm tree. Its filename was
vfs-kill-put_inode.patch
This patch was dropped because it was merged into mainline or a subsystem tree
The current -mm tree may be found at http://userweb.kernel.org/~akpm/mmotm/
------------------------------------------------------
Subject: vfs: kill->put_inode
From: Christoph Hellwig <hch@xxxxxx>
With the patch to affs killing the last put_inode() instance we can finally,
after many years of transition kill this racy and awkward interface.
(It's kinda funny that even the description in
Documentation/filesystems/vfs.txt was entirely wrong..)
Also remove a very misleading comment above the defintion of struct
super_operations.
