Technical description

In the Linux kernel, the following vulnerability has been resolved:

scsi: core: Remove the /proc/scsi/${proc_name} directory earlier

Remove the /proc/scsi/${proc_name} directory earlier to fix a race

condition between unloading and reloading kernel modules. This fixes a bug

introduced in 2009 by commit 77c019768f06 ("[SCSI] fix /proc memory leak in

the SCSI core").

Fix the following kernel warning:
