* [XFS] cleanup vnode use in dmapi callsChristoph Hellwig2008-04-17

* [XFS] Use power-of-2 sized buffers to reduce overheadDavid Chinner2008-04-17
| | | | | | | | | | | | | | | | | | Now that the ktrace_enter() code is using atomics, the non-power-of-2 buffer sizes - which require modulus operations to get the index - are showing up as using substantial CPU in the profiles. Force the buffer sizes to be rounded up to the nearest power of two and use masking rather than modulus operations to convert the index counter to the buffer index. This reduces ktrace_enter overhead to 8% of a CPU time, and again almost halves the trace intensive test runtime.

* [XFS] Use atomic counters for ktrace buffer indexesDavid Chinner2008-04-17
| | | | | | | | | | | | | | | ktrace_enter() is consuming vast amounts of CPU time due to the use of a single global lock for protecting buffer index increments. Change it to use per-buffer atomic counters - this reduces ktrace_enter() overhead during a trace intensive test on a 4p machine from 58% of all CPU time to 12% and halves test runtime.

* [XFS] Update c/mtime correctly on truncatesDavid Chinner2008-04-17
| | | | | | | | | | | | | | | | | | XFS changes the c/mtime of an inode when truncating it to the same size. The c/mtime is only supposed to change if the size is changed. Not to be confused with ftruncate, where the c/mtime is supposed to be changed even if the size is not changed. The Linux VFS encodes this semantic difference in the flags it sends down to ->setattr, which XFS currently ignores. We need to make XFS pay attention to the VFS flags and hence Do The Right Thing.

* [XFS] don't encode parent in nfs filehandles unless nessecaryChristoph Hellwig2008-04-17
| | | | | | | | | | | | | As Dave pointed out after the export ops changes we now always encode the parent into the filehandle for regular files, but it's not actually needed when the filesystem is export with no_subtree_check. This one-liner fixes xfs_fs_encode_fh to skip encoding the parent unless nessecary.

| | | | | | | | | | | | | | | Instead of of xfs_get_dir_entry use a macro to get the xfs_inode from the dentry in the callers and grab the reference manually. Only grab the reference once as it's fine to keep it over the dmapi calls.

* [XFS] Use atomics for iclog reference countingDavid Chinner2008-04-17
| | | | | | | | | | | | | | | | | | | | | | | | | | Now that we update the log tail LSN less frequently on transaction completion, we pass the contention straight to the global log state lock (l_iclog_lock) during transaction completion. We currently have to take this lock to decrement the iclog reference count. there is a reference count on each iclog, so we need to take þhe global lock for all refcount changes. When large numbers of processes are all doing small trnasctions, the iclog reference counts will be quite high, and the state change that absolutely requires the l_iclog_lock is the except rather than the norm. Change the reference counting on the iclogs to use atomic_inc/dec so that we can use atomic_dec_and_lock during transaction completion and avoid the need for grabbing the l_iclog_lock for every reference count decrement except the one that matters - the last.

* [XFS] Prevent AIL lock contention during transaction completionDavid Chinner2008-04-17
| | | | | | | | | | | | | | | | | | | | | | | | When hundreds of processors attempt to commit transactions at the same time, they can contend on the AIL lock when updating the tail LSN held in the in-core log structure. At the moment, the tail LSN is only needed when actually writing out an iclog, so it really does not need to be updated on every single transaction completion - only those that result in switching iclogs and flushing them to disk. The result is that we reduce the number of times we need to grab the AIL lock and the log grant lock by up to two orders of magnitude on large processor count machines. The problem has previously been hidden by AIL lock contention walking the AIL list which was recently solved and uncovered this issue.

* [XFS] Remove the xfs_icluster structureDavid Chinner2008-04-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Remove the xfs_icluster structure and replace with a radix tree lookup. We don't need to keep a list of inodes in each cluster around anymore as we can look them up quickly when we need to. The only time we need to do this now is during inode writeback. Factor the inode cluster writeback code out of xfs_iflush and convert it to use radix_tree_gang_lookup() instead of walking a list of inodes built when we first read in the inodes. This remove 3 pointers from each xfs_inode structure and the xfs_icluster structure per inode cluster. Hence we reduce the cache footprint of the xfs_inodes by between 5-10% depending on cluster sparseness. To be truly efficient we need a radix_tree_gang_lookup_range() call to stop searching once we are past the end of the cluster instead of trying to find a full cluster's worth of inodes.

* [XFS] Don't block pdflush when writing back inodesDavid Chinner2008-04-17
| | | | | | | | | | | | | | | | | | | | | | | | When pdflush is writing back inodes, it can get stuck on inode cluster buffers that are currently under I/O. This occurs when we write data to multiple inodes in the same inode cluster at the same time. Effectively, delayed allocation marks the inode dirty during the data writeback. Hence if the inode cluster was flushed during the writeback of the first inode, the writeback of the second inode will block waiting for the inode cluster write to complete before writing it again for the newly dirtied inode. Basically, we want to avoid this from happening so we don't block pdflush and slow down all of writeback. Hence we introduce a non-blocking async inode flush flag that pdflush uses. If this flag is set, we use non-blocking operations (e.g. try locks) whereever we can to avoid blocking or extra I/O being issued.

If the inode flush lock is not already held and there is an outstanding xfs_iflush_done() then we might free the inode prematurely.

| | * | | rfkill: Fix device type check when toggling statesCarlos Corbacho2008-04-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | rfkill_switch_all() is supposed to only switch all the interfaces of a given type, but does not actually do this; instead, it just switches everything currently in the same state. Add the necessary type check in. (This fixes a bug I've been seeing while developing an rfkill laptop driver, with both bluetooth and wireless simultaneously changing state after only pressing either KEY_WLAN or KEY_BLUETOOTH).

| | * | | ssb: Fix usage of struct device used for DMAingMichael Buesch2008-04-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This fixes DMA on architectures where DMA is nontrivial, like PPC64. We must use the host-device's (PCI) struct device for any DMA operation instead of the SSB device. For this we add a new struct device pointer to the SSB device structure that will always point to the right device for DMAing. Without this patch b43 and b44 drivers won't work on complex-DMA architectures, that for example need dev->archdata for DMA operations.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This allows for the correct initial values to be uploaded to bcm4303 devices. It should be correct, but I can't reliably test this as I suspect there's something going wrong with an hardware rfkill switch on my laptop. Please test.

| | * | | rtl8187: Add missing priv->vif assignmentsHerton Ronaldo Krzesinski2008-04-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds missing priv->vif assignments after "mac80211: don't use interface indices in drivers" change. As rtl8180, rtl8187 also needs priv->vif to be set, as without this an oops can happen in rtl8187_tx function (priv->vif is passed to ieee80211_rts_duration).

| * | | | netconsole: only set CON_PRINTBUFFER if the user specifies a netconsoleMichael Ellerman2008-04-15
| |/ / / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since 0bcc1816188e570bde1d56a208996660f2633ae0 (netconsole: Support dynamic reconfiguration using configfs), the netconsole is always registered, regardless of whether the user actually specified a netconsole configuration on the command line. However because netconsole has CON_PRINTBUFFER set, when it is registered it causes the printk buffer to be replayed to all consoles. When there is no netconsole configured this is a) pointless, and b) somewhat annoying for the user of the existing console. So instead we should only set CON_PRINTBUFFER if there is a netconsole configuration found on the command line. This retains the existing behaviour if a netconsole is setup by the user, and avoids spamming other consoles when we're only registering for the dynamic netconsole case.
