2011-08-19drivers/ata/sata_dwc_460ex.c: add missing kfreeJulia Lawall
Currently, error handling code in this function calls the function sata_dwc_port_stop, but this function has essentially no effect if hsdevp has not been stored in ap, which is the case throughout this function. The only effect is to print a debugging message including ap->print_id. The code is rewritten to not call sata_dwc_port_stop, but instead to jump to a local label that prints the original error message and the print_id information. In the case where hsdevp has been already allocated (but not yet stored in ap), this value is freed as well. A simplified version of the semantic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> @exists@ local idexpression x; statement S,S1; expression E; identifier fl; expression *ptr != NULL; @@ x = \(kmalloc\|kzalloc\|kcalloc\)(...); ... if (x == NULL) S <... when != x when != if (...) { <+...kfree(x)...+> } when any when != true x == NULL x->fl ...> ( if (x == NULL) S1 | if (...) { ... when != x when forall ( return \(0\|<+...x...+>\|ptr\); | * return ...; ) } ) // </smpl> Signed-off-by: Julia Lawall <julia@diku.dk> Signed-off-by: Jeff Garzik <jgarzik@pobox.com>

2011-08-17Btrfs: detect wether a device supports discardJosef Bacik
We have a problem where if a user specifies discard but doesn't actually support it we will return EOPNOTSUPP from btrfs_discard_extent. This is a problem because this gets called (in a fashion) from the tree log recovery code, which has a nice little BUG_ON(ret) after it, which causes us to fail the tree log replay. So instead detect wether our devices support discard when we're adding them and then don't issue discards if we know that the device doesn't support it. And just for good measure set ret = 0 in btrfs_issue_discard just in case we still get EOPNOTSUPP so we don't screw anybody up like this again.

CONFIG_TASKSTATS just had a change to use netlink, including a change to "depends on NET". Since "select" does not follow dependencies, KVM also needs to depend on NET to prevent build errors when CONFIG_NET is not enabled. Sample of the reported "undefined reference" build errors: taskstats.c:(.text+0x8f686): undefined reference to `nla_put' taskstats.c:(.text+0x8f721): undefined reference to `nla_reserve' taskstats.c:(.text+0x8f8fb): undefined reference to `init_net' taskstats.c:(.text+0x8f905): undefined reference to `netlink_unicast' taskstats.c:(.text+0x8f934): undefined reference to `kfree_skb' taskstats.c:(.text+0x8f9e9): undefined reference to `skb_clone' taskstats.c:(.text+0x90060): undefined reference to `__alloc_skb' taskstats.c:(.text+0x901e9): undefined reference to `skb_put' taskstats.c:(.init.text+0x4665): undefined reference to `genl_register_family' taskstats.c:(.init.text+0x4699): undefined reference to `genl_register_ops' taskstats.c:(.init.text+0x4710): undefined reference to `genl_unregister_ops' taskstats.c:(.init.text+0x471c): undefined reference to `genl_unregister_family' Signed-off-by: Randy Dunlap <rdunlap@xenotime.net> Signed-off-by: Marcelo Tosatti <mtosatti@redhat.com>

2011-08-16gma500: kill MIPI interface typesAlan Cox
Kirill Shutemov found problems with the non-upstream IMG driver where the use of extra DRM encoder/connector types caused random crashes when the DRM layer tried to display their matching name. This removes the MIPI types matching the changes Pauli Nieminen made to the non upstream driver set. As Pauli points out: " MIPI (or DSI) is protocol specification on top of LVDS serial bus. That makes it resonable to call MIPI connectors and encoders LVDS." (and indeed they may also be HDMI convertors or similar when we want to report a more useful to end user result) Signed-off-by: Alan Cox <alan@linux.intel.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
