2010-08-05cgroupfs: create /sys/fs/cgroup to mount cgroupfs onGreg KH1-1/+12
We really shouldn't be asking userspace to create new root filesystems. So follow along with all of the other in-kernel filesystems, and provide a mount point in sysfs. For cgroupfs, this should be in /sys/fs/cgroup/ This change provides that mount point when the cgroup filesystem is registered in the kernel.

2010-08-05Driver core: Add BUS_NOTIFY_BIND_DRIVERMagnus Damm2-3/+9
Add BUS_NOTIFY_BIND_DRIVER as a bus notifier event. For driver binding/unbinding we with this in place have the following bus notifier events: - BUS_NOTIFY_BIND_DRIVER - before ->probe() - BUS_NOTIFY_BOUND_DRIVER - after ->probe() - BUS_NOTIFY_UNBIND_DRIVER - before ->remove() - BUS_NOTIFY_UNBOUND_DRIVER - after ->remove() The event BUS_NOTIFY_BIND_DRIVER allows bus code to be notified that ->probe() is about to be called. Useful for bus code that needs to setup hardware before the driver gets to run. With this in place platform drivers can be loaded and unloaded as modules and the new BIND event allows bus code to control for instance device clocks that must be enabled before the driver can be executed. Without this patch there is no way for the bus code to get notified that a modular driver is about to be probed.

2010-08-05Driver core: Drop __must_check from bus_for_each_drv()Jean Delvare1-3/+2
There is little rationale for marking bus_for_each_drv() __must_check. It is more of an iteration helper than a real function. You don't know in advance which callback it will be used on, so you have no clue how important it can be to check the returned value. In practice, this helper function can be used for best-effort tasks. As a matter of fact, bus_for_each_dev() is not marked __must_check. So remove it from bus_for_each_drv() as well. This is the same that was done back in October 2006 by Russell King for device_for_each_child(), for exactly the same reasons.

2010-08-05ext4: Adding error check after calling ext4_mb_regular_allocator()Aditya Kali1-17/+17
If the bitmap block on disk is bad, ext4_mb_load_buddy() returns an error. This error is returned to the caller, ext4_mb_regular_allocator() and then to ext4_mb_new_blocks(). But ext4_mb_new_blocks() did not check for the return value of ext4_mb_regular_allocator() and would repeatedly try to load the bitmap block. The fix simply catches the return value and exits out of the 'repeat' loop after cleanup. We also take the opportunity to clean up the error handling in ext4_mb_new_blocks().

Fix this leftover TODO from the cfg80211 conversion by doing a scan if cfg80211 didn't pass in the BSSID for us. Since the scan code uses so much of the cfg80211_scan_request structure to build up the firmware command, we just fake one when the scan request is triggered internally.

In data=journal mode, we still use block_write_begin() to prepare page for writing. This function can occasionally mark buffer dirty which violates journalling assumptions - when a buffer is part of a transaction, it should be dirty and a buffer can be already part of a forget list of some transaction when block_write_begin() gets called. This violation of journalling assumptions then results in "JBD: Spotted dirty metadata buffer..." warnings. In fact, temporary dirtying the buffer while the page is still locked does not really cause problems to the journalling because we won't write the buffer until the page gets unlocked.

2010-08-05DNS: Separate out CIFS DNS Resolver codeWang Lei14-205/+708
Separate out the DNS resolver key type from the CIFS filesystem into its own module so that it can be made available for general use, including the AFS filesystem module. This facility makes it possible for the kernel to upcall to userspace to have it issue DNS requests, package up the replies and present them to the kernel in a useful form. The kernel is then able to cache the DNS replies as keys can be retained in keyrings. Resolver keys are of type "dns_resolver" and have a case-insensitive description that is of the form "[<type>:]<domain_name>". The optional <type> indicates the particular DNS lookup and packaging that's required. The <domain_name> is the query to be made. If <type> isn't given, a basic hostname to IP address lookup is made, and the result is stored in the key in the form of a printable string consisting of a comma-separated list of IPv4 and IPv6 addresses. This key type is supported by userspace helpers driven from /sbin/request-key and configured through /etc/request-key.conf. The cifs.upcall utility is invoked for UNC path server name to IP address resolution. The CIFS functionality is encapsulated by the dns_resolve_unc_to_ip() function, which is used to resolve a UNC path to an IP address for CIFS filesystem. This part remains in the CIFS module for now. See the added Documentation/networking/dns_resolver.txt for more information.
