2012-01-03switch device_get_devnode() and ->devnode() to umode_t *Al Viro
both callers of device_get_devnode() are only interested in lower 16bits and nobody tries to return anything wider than 16bit anyway. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
2012-01-03switch ->create() to umode_tAl Viro
vfs_create() ignores everything outside of 16bit subset of its mode argument; switching it to umode_t is obviously equivalent and it's the only caller of the method Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
2012-01-03switch vfs_mkdir() and ->mkdir() to umode_tAl Viro
vfs_mkdir() gets int, but immediately drops everything that might not fit into umode_t and that's the only caller of ->mkdir()... Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>

2012-01-03vfs: fix the stupidity with i_dentry in inode destructorsAl Viro
Seeing that just about every destructor got that INIT_LIST_HEAD() copied into it, there is no point whatsoever keeping this INIT_LIST_HEAD in inode_init_once(); the cost of taking it into inode_init_always() will be negligible for pipes and sockets and negative for everything else. Not to mention the removal of boilerplate code from ->destroy_inode() instances... Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
2012-01-03Revert "rtc: Disable the alarm in the hardware"Linus Torvalds
This reverts commit c0afabd3d553c521e003779c127143ffde55a16f. It causes failures on Toshiba laptops - instead of disabling the alarm, it actually seems to enable it on the affected laptops, resulting in (for example) the laptop powering on automatically five minutes after shutdown. There's a patch for it that appears to work for at least some people, but it's too late to play around with this, so revert for now and try again in the next merge window.

2011-12-27watchdog: iTCO_wdt.c - problems with newer hardware due to SMI clearing (part 2)Wim Van Sebroeck
Redhat Bugzilla: Bug 727875 - TCO_EN bit is disabled by TCO driver The previous patch breaks reset watchdog behaviour on the older hardware. It is therefor better to make sure that the behaviour for older hardware (<=ICH5 or 6300ESB) is preserved and that the behaviour for newer hardware is changed. We therefor use the iTCO_version to see if we need the clearing of the SMI_TCO_EN bit in the SMI_EN register. So the new behaviour becomes: turn_SMI_watchdog_clear_off=0 -> Do not turn off SMI clearing watchdog. turn_SMI_watchdog_clear_off=1 -> Turn off SMI clearing watchdog when iTCO_version=1 (ICHO till ICH5 + 6300ESB only) turn_SMI_watchdog_clear_off=2 -> Turn off SMI clearing watchdog.

2011-12-23md/bitmap: It is OK to clear bits during recovery.NeilBrown
commit d0a4bb492772ce5c4bdfba3744a99ed6f6fb238f introduced a regression which is annoying but fairly harmless. When writing to an array that is undergoing recovery (a spare in being integrated into the array), writing to the array will set bits in the bitmap, but they will not be cleared when the write completes. For bits covering areas that have not been recovered yet this is not a problem as the recovery will clear the bits. However bits set in already-recovered region will stay set and never be cleared. This doesn't risk data integrity. The only negatives are: - next time there is a crash, more resyncing than necessary will be done. - the bitmap doesn't look clean, which is confusing. While an array is recovering we don't want to update the 'events_cleared' setting in the bitmap but we do still want to clear bits that have very recently been set - providing they were written to the recovering device. So split those two needs - which previously both depended on 'success' and always clear the bit of the write went to all devices. Signed-off-by: NeilBrown <neilb@suse.de>
2011-12-23md: don't give up looking for spares on first failure-to-addNeilBrown
Before performing a recovery we try to remove any spares that might not be working, then add any that might have become relevant. Currently we abort on the first spare that cannot be added. This is a false optimisation. It is conceivable that - depending on rules in the personality - a subsequent spare might be accepted. Also the loop does other things like count the available spares and reset the 'recovery_offset' value. If we abort early these might not happen properly. So remove the early abort. In particular if you have an array what is undergoing recovery and which has extra spares, then the recovery may not restart after as reboot as the could of 'spares' might end up as zero.

2011-12-23md/raid5: ensure correct assessment of drives during degraded reshape.NeilBrown
While reshaping a degraded array (as when reshaping a RAID0 by first converting it to a degraded RAID4) we currently get confused about which devices are in_sync. In most cases we get it right, but in the region that is being reshaped we need to treat non-failed devices as in-sync when we have the data but haven't actually written it out yet.

2011-12-23md/linear: fix hot-add of devices to linear arrays.NeilBrown
commit d70ed2e4fafdbef0800e73942482bb075c21578b broke hot-add to a linear array. After that commit, metadata if not written to devices until they have been fully integrated into the array as determined by saved_raid_disk. That patch arranged to clear that field after a recovery completed. However for linear arrays, there is no recovery - the integration is instantaneous. So we need to explicitly clear the saved_raid_disk field. Signed-off-by: NeilBrown <neilb@suse.de>

Commit e133e737 didn't correctly fix the integer overflow issue. - unsigned int required_size; + u64 required_size; ... required_size = mode_cmd->pitch * mode_cmd->height; - if (unlikely(required_size > dev_priv->vram_size)) { + if (unlikely(required_size > (u64) dev_priv->vram_size)) { Note that both pitch and height are u32. Their product is still u32 and would overflow before being assigned to required_size. A correct way is to convert pitch and height to u64 before the multiplication. required_size = (u64)mode_cmd->pitch * (u64)mode_cmd->height; This patch calls the existing vmw_kms_validate_mode_vram() for validation.
