| * CRED: Fix commit_creds() on a process that has no mmDavid Howells2009-01-08
| | | | | | | | | | | | | | | | | | | | Fix commit_creds()'s handling of a process that has no mm (such as one that is calling or has called daemonize()). commit_creds() should check to see if task->mm is not NULL before calling set_dumpable() on it.

| * | [S390] hvc_iucv: Special handling of IUCV HVC devicesHendrik Brueckner2009-01-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch introduces special handling of the IUCV HVC console device. If the first IUCV HVC terminal is used as (preferred) Linux console, and needs some special handling for hangup. The hvc_iucv_private structure contains a flag to indicate whether a IUCV HVC device is used as a console. A terminal acting as "console" behaves different if a tty hangup occurs: If the iucv communication path is severed, a tty hangup is not triggered (because the HVC layer does not notify its back-end in that case). Instead, the console session is left unchanged and the IUCV HVC device is reset to allow re-connects. Note: Any output between the disconnect and a re-connect is discarded.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If CONFIG_DEBUG_FS is disabled debugfs_create_file returns -ENODEV instead of zero.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When the connection between host and storage server is lost, the dasd device driver usually blocks all I/O on affected devices and waits for them to reappear. In some setups however it would be better if the I/O is returned as error so that device can be recovered by some other means, eg. in a raid or multipath setup.

This driver implements support for this within the standard LED class. Platform initialisation code should configure the LED hardware in the init callback provided by the WM8350 core driver. The callback should use wm8350_isink_set_flash(), wm8350_dcdc25_set_mode() and wm8350_dcdc_set_slot() to configure the operating parameters of the regulators for their hardware and then then use wm8350_register_led() to instantiate the LED driver. This driver was originally written by Liam Girdwood, though it has been extensively modified since then.

| * | | Btrfs: explicitly mark the tree log root for writebackChris Mason2009-01-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Each subvolume has an extent_state_tree used to mark metadata that needs to be sent to disk while syncing the tree. This is used in addition to the dirty bits on the pages themselves so that a single subvolume can be sent to disk efficiently in disk order. Normally this marking happens in btrfs_alloc_free_block, which also does special recording of dirty tree blocks for the tree log roots. Yan Zheng noticed that when the root of the log tree is allocated, it is added to the wrong writeback list. The fix used here is to explicitly set it dirty as part of tree log creation.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | Checksum verification happens in a helper thread, and there is no need to mess with interrupts. This switches to kmap() instead. Signed-off-by: Chris Mason <chris.mason@oracle.com>
