* [PATCH] kprobes-changed-from-using-spinlock-to-mutex fixKeshavamurthy Anil S2006-01-10

* [PATCH] kprobes: changed from using spinlock to mutexAnil S Keshavamurthy2006-01-10
| | | | | | | | | | | | | | | Since Kprobes runtime exception handlers is now lock free as this code path is now using RCU to walk through the list, there is no need for the register/unregister{_kprobe} to use spin_{lock/unlock}_isr{save/restore}. The serialization during registration/unregistration is now possible using just a mutex. In the above process, this patch also fixes a minor memory leak for x86_64 and powerpc.

* [PATCH] kprobes: cleanup include/asm/kprobes.hAnil S Keshavamurthy2006-01-10
| | | | | | | | | | | | | | | The arch specific kprobes.h files never gets included when CONFIG_KPROBES is turned off. Hence check for CONFIG_KPROBES is not appropriate here in this arch specific kprobes.h files. Also the below defined function kprobes_exception_notify() is not needed when CONFIG_KPROBES is off. Compile tested for both CONFIG_KPROBES=y and N.

* [PATCH] kprobes: enable funcions only for required archAnil S Keshavamurthy2006-01-10
| | | | | | | | | | | | | | | Kernel/kprobes.c defines get_insn_slot() and free_insn_slot() which are currently required _only_ for x86_64 and powerpc (which has no-exec support). FYI, get{free}_insn_slot() functions manages the memory page which is mapped as executable, required for instruction emulation. This patch moves those two functions under __ARCH_WANT_KPROBES_INSN_SLOT and defines __ARCH_WANT_KPROBES_INSN_SLOT in arch specific kprobes.h file.

* [PATCH] Export ktime_get_ts()Matt Helsley2006-01-10
| | | | | | | | | | | | | | | | | | | This series removes the getnstimestamp() function from kernel/time.c in favor of kernel/hrtimer.c's ktime_get_ts() function which currently does exactly the same thing: retrieves a high-resolution (ns) timespec structure and performs the wall_to_monotonic adjustment. This patch: Export ktime_get_ts() to be used as a timestamp function since it uses getnstimefoday() and does the wall_to_monotonic adjustment.

* [PATCH] per-mountpoint noatime/nodiratimeChristoph Hellwig2006-01-10
| | | | | | | | | | | | | | | | | | | | Turn noatime and nodiratime into per-mount instead of per-sb flags. After all the preparations this is a rather trivial patch. The mount code needs to treat the two options as per-mount instead of per-superblock, and touch_atime needs to be changed to check the new MNT_ flags in addition to the MS_ flags that are kept for filesystems that are always noatime/nodiratime but not user settable anymore. Besides that core code only nfs needed an update because it's leaving atime updates to the server and thus sets the S_NOATIME flag on every inode, but needs to know whether it's a real noatime mount for an getattr optimization. While we're at it I've killed the IS_NOATIME/IS_NODIRATIME macros that were only used by touch_atime.

* [PATCH] sanitize building of fs/compat_ioctl.cChristoph Hellwig2006-01-10
| | | | | | | | | | | | | | | | | | | | | | | Now that all these entries in the arch ioctl32.c files are gone [1], we can build fs/compat_ioctl.c as a normal object and kill tons of cruft. We need a special do_ioctl32_pointer handler for s390 so the compat_ptr call is done. This is not needed but harmless on all other architectures. Also remove some superflous includes in fs/compat_ioctl.c Tested on ppc64. [1] parisc still had it's PPP handler left, which is not fully correct for ppp and besides that ppp uses the generic SIOCPRIV ioctl so it'd kick in for all netdevice users. We can introduce a proper handler in one of the next patch series by adding a compat_ioctl method to struct net_device but for now let's just kill it - parisc doesn't compile in mainline anyway and I don't want this to block this patchset.

It's based on the x86_64 code which needed a little massaging to be endian-clean. parisc used COMPAT_IOCTL or generic w_long handlers for these whichce is wrong and can't work because the ioctls encode sizeof(unsigned long) in their ioctl number. parisc also duplicated COMPAT_IOCTL entries for other rtc ioctls which I remove in this patch, too.

* [PATCH] move xattr permission checks into the VFSakpm@osdl.org2006-01-10
| | | | | | | | | | | | | | | | | | | | ) From: Christoph Hellwig <hch@lst.de> The xattr code has rather complex permission checks because the rules are very different for different attribute namespaces. This patch moves as much as we can into the generic code. Currently all the major disk based filesystems duplicate these checks, while many minor filesystems or network filesystems lack some or all of them. To do this we need defines for the extended attribute names in common code, I moved them up from JFS which had the nicest defintions.
