[PATCH] proc: modify proc_pident_lookup to be completely table driven
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. Signed-off-by: Eric W.
