The patch titled
scsi: use non-racy method for proc entries creation
has been removed from the -mm tree. Its filename was

------------------------------------------------------
Subject: scsi: use non-racy method for proc entries creation
From: "Denis V. Lunev" <den@xxxxxxxxxx>
Use proc_create() to make sure that ->proc_fops be setup before gluing PDE to
main tree.
Add correct ->owner to proc_fops to fix reading/module unloading race.
