here we actually *want* ->d_op for root; setting it allows to get rid of kludge in v9fs_kill_super() since now we have proper ->d_release() for root and don't need to call it manually. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>

Coda ->d_revalidate() actually checks for root, ->d_delete() is irrelevant. So we can use the same d_op for all coda dentries Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>

2011-01-12net/ceph: make ceph_msgr_wq non-reentrantTejun Heo
ceph messenger code does a rather complex dancing around multithread workqueue to make sure the same work item isn't executed concurrently on different CPUs. This restriction can be provided by workqueue with WQ_NON_REENTRANT. Make ceph_msgr_wq non-reentrant workqueue with the default concurrency level and remove the QUEUED/BUSY logic. * This removes backoff handling in con_work() but it couldn't reliably block execution of con_work() to begin with - queue_con() can be called after the work started but before BUSY is set. It seems that it was an optimization for a rather cold path and can be safely removed. * The number of concurrent work items is bound by the number of connections and connetions are independent from each other. With the default concurrency level, different connections will be executed independently.

2011-01-12ceph: drop redundant r_mds fieldSage Weil
The r_mds field is redundant, since we can find the same information at r_session->s_mds, and when r_session is NULL then r_mds is meaningless. Signed-off-by: Sage Weil <sage@newdream.net>
2011-01-12ceph: implement DIRLAYOUTHASH feature to get dir layout from MDSSage Weil
This implements the DIRLAYOUTHASH protocol feature, which passes the dir layout over the wire from the MDS. This gives the client knowledge of the correct hash function to use for mapping dentries among dir fragments. Note that if this feature is _not_ present on the client but is on the MDS, the client may misdirect requests. This will result in a forward and degrade performance. It may also result in inaccurate NFS filehandle generation, which will prevent fh resolution when the inode is not present in the client cache and the parent directories have been fragmented. Signed-off-by: Sage Weil <sage@newdream.net>
2011-01-12ceph: add dir_layout to inodeSage Weil
Add a ceph_dir_layout to the inode, and calculate dentry hash values based on the parent directory's specified dir_hash function. This is needed because the old default Linux dcache hash function is extremely week and leads to a poor distribution of files among dir fragments. Signed-off-by: Sage Weil <sage@newdream.net>

2011-01-12cpuidle/x86/perf: fix power:cpu_idle double end events and throw cpu_idle ↵Thomas Renninger
events from the cpuidle layer Currently intel_idle and acpi_idle driver show double cpu_idle "exit idle" events -> this patch fixes it and makes cpu_idle events throwing less complex. It also introduces cpu_idle events for all architectures which use the cpuidle subsystem, namely: - arch/arm/mach-at91/cpuidle.c - arch/arm/mach-davinci/cpuidle.c - arch/arm/mach-kirkwood/cpuidle.c - arch/arm/mach-omap2/cpuidle34xx.c - arch/drivers/acpi/processor_idle.c (for all cases, not only mwait) - arch/x86/kernel/process.c (did throw events before, but was a mess) - drivers/idle/intel_idle.c (did throw events before) Convention should be: Fire cpu_idle events inside the current pm_idle function (not somewhere down the the callee tree) to keep things easy. Current possible pm_idle functions in X86: c1e_idle, poll_idle, cpuidle_idle_call, mwait_idle, default_idle -> this is really easy is now. This affects userspace: The type field of the cpu_idle power event can now direclty get mapped to: /sys/devices/system/cpu/cpuX/cpuidle/stateX/{name,desc,usage,time,...} instead of throwing very CPU/mwait specific values. This change is not visible for the intel_idle driver. For the acpi_idle driver it should only be visible if the vendor misses out C-states in his BIOS. Another (perf timechart) patch reads out cpuidle info of cpu_idle events from: /sys/.../cpuidle/stateX/*, then the cpuidle events are mapped to the correct C-/cpuidle state again, even if e.g. vendors miss out C-states in their BIOS and for example only export C1 and C3. -> everything is fine.

2011-01-12IB/mlx4: Handle protocol field in multicast tableAleksey Senin
The newest device firmware stores IB vs. Ethernet protocol in two bits in members_count field of multicast group table (0: Infiniband, 1: Ethernet). When changing the QP members count for a multicast group, it important not to reset this information. When calling multicast attach first time, the protocol type should be specified. In this patch we always set it IB, but in the future we will handle Ethernet too. When looking for a QP, the protocol type shoud be checked too.

2011-01-13olpc_battery: Fix up XO-1.5 properties listSascha Silbe
The patches adding support for CURRENT_NOW, VOLTAGE_NOW, CHARGE_NOW and CHARGE_FULL_DESIGN were based on a tree not including c566d299 ("olpc_battery: Ambient temperature is not available on XO-1.5") and therefore only modified the then-common, now-XO-1 properties list. This patch adds the new properties to XO-1.5 as well. Signed-off-by: Sascha Silbe <sascha-pgp@silbe.org> Signed-off-by: Anton Vorontsov <cbouatmailru@gmail.com>

2011-01-12i2c-bfin-twi: move setup to the earlier subsys initcallMichael Hennerich
Some systems using this bus sometimes have very basic devices such as regulators on the bus, so the I2C bus master needs to be loaded early. This also matches the behavior of many other I2C bus master drivers. Therefore initialize via subsys_initcall().
