2009-05-09New helper: deactivate_locked_super()Al Viro2-12/+35
Does equivalent of up_write(&s->s_umount); deactivate_super(s); However, it does not does not unlock it until it's all over. As the result, it's safe to use to dispose of new superblock on ->get_sb() failure exits - nobody will see the sucker until it's all over. Equivalent using up_write/deactivate_super is safe for that purpose if superblock is either safe to use or has NULL ->s_root when we unlock. Normally filesystems take the required precautions, but a) we do have bugs in that area in some of them. b) up_write/deactivate_super sequence is extremely common, so the helper makes sense anyway.

2009-05-09reiserfs: remove privroot hiding in lookupJeff Mahoney4-28/+16
With Al Viro's patch to move privroot lookup to fs mount, there's no need to have special code to hide the privroot in reiserfs_lookup. I've also cleaned up the privroot hiding in reiserfs_readdir_dentry and removed the last user of reiserfs_xattrs().

2009-05-09reiserfs: fixup xattr_root cachingJeff Mahoney3-29/+48
The xattr_root caching was broken from my previous patch set. It wouldn't cause corruption, but could cause decreased performance due to allocating a larger chunk of the journal (~ 27 blocks) than it would actually use. This patch loads the xattr root dentry at xattr initialization and creates it on-demand. Since we're using the cached dentry, there's no point in keeping lookup_or_create_dir around, so that's removed.

2009-05-09reiserfs: Expand i_mutex to enclose lookup_one_lenJeff Mahoney1-18/+14
2.6.30-rc3 introduced some sanity checks in the VFS code to avoid NFS bugs by ensuring that lookup_one_len is always called under i_mutex. This patch expands the i_mutex locking to enclose lookup_one_len. This was always required, but not not enforced in the reiserfs code since it does locking around the xattr interactions with the xattr_sem. This is obvious enough, and it survived an overnight 50 thread ACL test. Signed-off-by: Jeff Mahoney <jeffm@suse.com> Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>

2009-05-09Revert driver core: move platform_data into platform_deviceGreg Kroah-Hartman3-11/+2
This reverts commit 006f4571a15fae3a0575f2a0f9e9b63b3d1012f8: This patch moves platform_data from struct device into struct platform_device, based on the two ideas: 1. Now all platform_driver is registered by platform_driver_register, which makes probe()/release()/... of platform_driver passed parameter of platform_device *, so platform driver can get platform_data from platform_device; 2. Other kind of devices do not need to use platform_data, we can decrease size of device if moving it to platform_device. Taking into consideration of thousands of files to be fixed and they can't be finished in one night(maybe it will take a long time), so we keep platform_data in device to allow two kind of cases coexist until all platform devices pass its platfrom data from platform_device->platform_data. All patches to do this kind of conversion are welcome. As we don't really want to do it, it was a bad idea.

2009-05-09ipvs: Fix IPv4 FWMARK virtual servicesSimon Horman2-4/+9
This fixes the use of fwmarks to denote IPv4 virtual services which was unfortunately broken as a result of the integration of IPv6 support into IPVS, which was included in 2.6.28. The problem arises because fwmarks are stored in the 4th octet of a union nf_inet_addr .all, however in the case of IPv4 only the first octet, corresponding to .ip, is assigned and compared. In other words, using .all = { 0, 0, 0, htonl(svc->fwmark) always results in a value of 0 (32bits) being stored for IPv4. This means that one fwmark can be used, as it ends up being mapped to 0, but things break down when multiple fwmarks are used, as they all end up being mapped to 0. As fwmarks are 32bits a reasonable fix seems to be to just store the fwmark in .ip, and comparing and storing .ip when fwmarks are used. This patch makes the assumption that in calls to ip_vs_ct_in_get() and ip_vs_sched_persist() if the proto parameter is IPPROTO_IP then we are dealing with an fwmark. I believe this is valid as ip_vs_in() does fairly strict filtering on the protocol and IPPROTO_IP should not be used in these calls unless explicitly passed when making these calls for fwmarks in ip_vs_sched_persist().

2009-05-08ACPI: suspend: don't let device _PS3 failure prevent suspendLen Brown1-5/+3
6328a57401dc5f5cf9931738eb7268fcd8058c49 "Enable PNPACPI _PSx Support, v3" added a call to acpi_bus_set_power(handle, ACPI_STATE_D3) to pnpacpi_disable_resource() before the existing call to evaluate _DIS on the device. This caused suspend to fail on the system in http://bugzilla.kernel.org/show_bug.cgi?id=13243 because the sanity check to verify we entered _PS3 failed on the serial port. As a work-around, that sanity check can be disabled system-wide with "acpi.power_nocheck=1" Or perhaps we should just shrug off the _PS3 failure and carry on with _DIS like we used to -- which is what this patch does.

2009-05-08ACPI: power: update error messageLen Brown1-1/+1
"Transitioning device [%s] to D%d" is not correct. We print this line when we attempted to transition the device, and it failed. So instead, print "Device [%s] failed to transition to D%d\n" This can happen under two conditions: 1. acpi_power_transition() fails when trying to handle the _ON/_OFF for associated power resource. 2. acpi_evaluate_object() on the explicit _PS0/_PS3 for that actual device could fail. this change clarifies, but doesn't fix http://bugzilla.kernel.org/show_bug.cgi?id=13243 Signed-off-by: Len Brown <len.brown@intel.com>
