This is the central patch of a cleanup series. In most cases there is no good reason why someone would want to use a dentry for itself. This series reflects that fact and embeds a struct path into nameidata. Together with the other patches of this series - it enforced the correct order of getting/releasing the reference count on <dentry,vfsmount> pairs - it prepares the VFS for stacking support since it is essential to have a struct path in every place where the stack can be traversed - it reduces the overall code size: without patch series: text data bss dec hex filename 5321639 858418 715768 6895825 6938d1 vmlinux with patch series: text data bss dec hex filename 5320026 858418 715768 6894212 693284 vmlinux This patch: Switch from nd->{dentry,mnt} to nd->path.{dentry,mnt} everywhere.

The warning issued by fs/binfmt_flat.c when the format handler is given a non-FLAT and non-script executable is annoying to say the least when working with FDPIC ELF objects. If you build a kernel that supports both FLAT and FDPIC ELFs on no-mmu, every time you execute an FDPIC ELF, the kernel spits out this message. While I understand a lot of newcomers to the no-mmu world screw up generation of FLAT binaries, this warning is not usable for systems that support more than just FLAT. Signed-off-by:

This is due to the use of the construct: *((long*)dst)++ = lc; Which is no longer legal since casts don't return an lvalue. The solution is to import the implementation from newlib, which is continually autotested together with GCC mainline, and uses the construct: *(long *) dst = lc; dst += 4; With this change, the generated code actually shrinks 76 bytes since gcc notices that it can use autoincrement for the move instruction in CRIS. text data bss dec hex filename 304 0 0 304 130 memset.old.o text data bss dec hex filename 228 0 0 228 e4 memset.o Since this is an import of a file from newlib, I'm not touching the formatting or correcting any checkpatch errors. Note also that even if the two files for the CRIS v10 and CRIS v32 are identical at the moment, it might be possible to tweak the CRIS v32 version. Thus, I'm not yet folding them into the same file, at least not until we've done some research on it.

This adds some new magic in the MODPOST phase for CONFIG_MARKERS. Analogous to the Module.symvers file, the build will now write a Module.markers file when CONFIG_MARKERS=y is set. This file lists the name, defining module, and format string of each marker, separated by \t characters. This simple text file can be used by offline build procedures for instrumentation code, analogous to how System.map and Module.symvers can be useful to have for kernels other than the one you are running right now. The strings are made easy to extract by having the __trace_mark macro define the name and format together in a single array called __mstrtab_* in the __markers_strings section. This is straightforward and reliable as long as the marker structs are always defined by this macro. It is an unreasonable amount of hairy work to extract the string pointers from the __markers section structs, which entails handling a relocation type for every machine under the sun.

RCU style multiple probes support for the Linux Kernel Markers. Common case (one probe) is still fast and does not require dynamic allocation or a supplementary pointer dereference on the fast path. - Move preempt disable from the marker site to the callback. Since we now have an internal callback, move the preempt disable/enable to the callback instead of the marker site. Since the callback change is done asynchronously (passing from a handler that supports arguments to a handler that does not setup the arguments is no arguments are passed), we can safely update it even if it is outside the preempt disable section. - Move probe arm to probe connection. Now, a connected probe is automatically armed. Remove MARK_MAX_FORMAT_LEN, unused. This patch modifies the Linux Kernel Markers API : it removes the probe "arm/disarm" and changes the probe function prototype : it now expects a va_list * instead of a "...". If we want to have more than one probe connected to a marker at a given time (LTTng, or blktrace, ssytemtap) then we need this patch. Without it, connecting a second probe handler to a marker will fail. It allow us, for instance, to do interesting combinations : Do standard tracing with LTTng and, eventually, to compute statistics with SystemTAP, or to have a special trigger on an event that would call a systemtap script which would stop flight recorder tracing.

This leads to .config hilarity, with net suddenly ending up in the SCSI menu: # # SCSI device support # # CONFIG_SCSI_DMA is not set # CONFIG_SCSI_NETLINK is not set CONFIG_PPP=y # CONFIG_PHONE is not set Curiously the SLHC select from PPP doesn't seem to happen, as there's no CONFIG_SLHC=y (only CONFIG_PPP=y gets set) -- Kconfig bug?

On alpha, ia64 and ppc64 only relocations to local data can go into read-only sections. The vast majority of module parameters use the global generic param_set_*/param_get_* functions, so the 'const' attribute for struct kernel_param is not only useless, but it also causes compile failures due to 'section type conflict' in those rare cases where param_set/get are local functions.
