The patch titled
proc: modify proc_pident_lookup to be completely table driven
has been added to the -mm tree. Its filename is
proc-modify-proc_pident_lookup-to-be-completely-table-driven.patch
See http://www.zip.com.au/~akpm/linux/patches/stuff/added-to-mm.txt to find
out what to do about this
------------------------------------------------------
Subject: proc: modify proc_pident_lookup to be completely table driven
From: "Eric W. Biederman" <ebiederm@xxxxxxxxxxxx>
Currently proc_pident_lookup gets the names and types from a table and then
has a huge switch statement to get the inode and file operations it needs.
That is silly and is becoming increasingly hard to maintain so I just put all
of the information in the table.
