Subject: [PATCH 0/4] remove PDE_DATA()
I found a bug [1] some days ago, which is because we want to use
inode->i_private to pass user private data. However, this is wrong
on proc fs. We provide a specific function PDE_DATA() to get user
private data. Actually, we can hide this detail by storing
PDE()->data into inode->i_private and removing PDE_DATA() completely.
The user could use inode->i_private to get user private data just
like debugfs does. This series is trying to remove PDE_DATA().

Muchun Song (4):
fs: proc: store PDE()->data into inode->i_private
fs: proc: replace PDE_DATA(inode) with inode->i_private
fs: proc: remove PDE_DATA()
fs: proc: use DEFINE_PROC_SHOW_ATTRIBUTE() to simplify the code
