Subject[PATCH] memory leak in scsi_proc.c (fixed patch error)
Hi,

fixed patch poster earlier. PINE's default editor munged it up. Also changed
the 8 spaces indentation to a tab character.

Sorry about that.

> If someone writes to a scsi adapter's /proc entry and that scsi adapter
> has not defined a proc_info() entry point, proc_scsi_write() will leak a
> page. Furthermore, no sense asking for a page if said proc_info() entry
> point does not exist. This patch fixes the above problem and patches
> cleanly against 2.4.4
