* fuse: add file handle to getattr operationMiklos Szeredi2007-10-18
| | | | | | | | | | | | | Add necessary protocol changes for supplying a file handle with the getattr operation. Step the API version to 7.9. This patch doesn't actually supply the file handle, because that needs some kind of VFS support, which we haven't yet been able to agree upon.

* fuse: fix race between getattr and writeMiklos Szeredi2007-10-18
| | | | | | | | | | | | | | | | | | | | | | | | | Getattr and lookup operations can be running in parallel to attribute changing operations, such as write and setattr. This means, that if for example getattr was slower than a write, the cached size attribute could be set to a stale value. To prevent this race, introduce a per-filesystem attribute version counter. This counter is incremented whenever cached attributes are modified, and the incremented value stored in the inode. Before storing new attributes in the cache, getattr and lookup check, using the version number, whether the attributes have been modified during the request's lifetime. If so, the returned attributes are not cached, because they might be stale. Thanks to Jakub Bogusz for the bug report and test program.

* ext3: support large blocksize up to PAGESIZETakashi Sato2007-10-18
| | | | | | | | | | | | | | | | | | | | | | | | | | | This patch set supports large block size(>4k, <=64k) in ext3 just enlarging the block size limit. But it is NOT possible to have 64kB blocksize on ext3 without some changes to the directory handling code. The reason is that an empty 64kB directory block would have a rec_len == (__u16)2^16 == 0, and this would cause an error to be hit in the filesystem. The proposed solution is treat 64k rec_len with a an impossible value like rec_len = 0xffff to handle this. The Patch-set consists of the following 2 patches. [1/2] ext3: enlarge blocksize - Allow blocksize up to pagesize [2/2] ext3: fix rec_len overflow - prevent rec_len from overflow with 64KB blocksize Now on 64k page ppc64 box runs with this patch set we could create a 64k block size ext3, and able to handle empty directory block.

* Redefine {un}register_hotcpu_notifier() !HOTPLUG_CPU stubsSatyam Sharma2007-10-18
| | | | | | | | | | | | | | | | | The return of the present "do {} while" based stub definition of register_hotcpu_notifier() cannot be checked. This makes the stub asymmetric w.r.t. the real HOTPLUG_CPU=y implementation that is int-returning. So let us redefine this to be consistent with the full version. Also do the same for unregister_hotcpu_notifier(). We cannot define these as static inline functions due to an existing GCC bug (#33172). So define as macros that return appropriately instead (int '0' for the register_hotcpu_notifier case and void for unregister_hotcpu_notifier).

* powerpc: add scaled time accountingMichael Neuling2007-10-18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds POWERPC specific hooks for scaled time accounting. POWER6 includes a SPURR register. The SPURR is based off the PURR register but is scaled based on CPU frequency and issue rates. This gives a more accurate account of the instructions used per task. The PURR and timebase will be constant relative to the wall clock, irrespective of the CPU frequency. This implementation reads the SPURR register in account_system_vtime which is only call called on context witch and hard and soft irq entry and exit. The percentage of user and system time is then estimated using the ratio of these accounted by the PURR. If the SPURR is not present, the PURR read. An earlier implementation of this patch read the SPURR whenever the PURR was read, which included the system call entry and exit path. Unfortunately this showed a performance regression on lmbench runs, so was re-implemented. I've included the lmbench results here when run bare metal on POWER6. 1st column is the unpatch results. 2nd column is the results using the below patch and the 3rd is the % diff of these results from the base. 4th and 5th columns are the results and % differnce from the base using the older patch (SPURR read in syscall entry/exit path).
