scsi: mpt: suppress debugobjects warning

proc 2/2: remove struct proc_dir_entry::owner

2009-03-30T21:14:44Z

Setting ->owner as done currently (pde->owner = THIS_MODULE) is racy as correctly noted at bug #12454. Someone can lookup entry with NULL ->owner, thus not pinning enything, and release it later resulting in module refcount underflow. We can keep ->owner and supply it at registration time like ->proc_fops and ->data. But this leaves ->owner as easy-manipulative field (just one C assignment) and somebody will forget to unpin previous/pin current module when switching ->owner. ->proc_fops is declared as "const" which should give some thoughts. ->read_proc/->write_proc were just fixed to not require ->owner for protection. rmmod'ed directories will be empty and return "." and ".." -- no harm. And directories with tricky enough readdir and lookup shouldn't be modular. We definitely don't want such modular code. Removing ->owner will also make PDE smaller. So, let's nuke it. Kudos to Jeff Layton for reminding about this, let's say, oversight. http://bugzilla.kernel.org/show_bug.cgi?id=12454 Signed-off-by: Alexey Dobriyan

[SCSI] mpt: fix disable lsi sas to use msi as default

2009-02-22T14:51:07Z

Impact: fix bug the third param in module_param(,,) is perm instead of default value. we still need to assign default at first. Also, the default is now zero not one, so fix the parameter text to reflect that. Signed-off-by: Yinghai Lu Acked-by: Kashyap Desai Signed-off-by: James Bottomley
