* Embed a struct path into struct nameidata instead of nd->{dentry,mnt}Jan Blunck2008-02-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* FLAT binaries: drop BINFMT_FLAT bad header magic warningMike Frysinger2008-02-14
| | | | | | | | | | | | | | | | | 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.

* cris: import memset.c from newlib: fixes compile error with newer (pre4.3) gccJesper Nilsson2008-02-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Adrian Bunk reported the following compile error with a SVN head GCC: ...

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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It looks like there's been a bug in the module parameter setup forever. The upshot doesn't really matter, because even if no parameters are ever set, we just call sym53c416_setup() three times, but the zero values in the arrays eventually cause nothing to happen. Unfortunately gcc has started to notice this now too: drivers/scsi/sym53c416.c: In function 'sym53c416_detect': drivers/scsi/sym53c416.c:624: warning: the address of 'sym53c416' will always evaluate as 'true' drivers/scsi/sym53c416.c:630: warning: the address of 'sym53c416_1' will always evaluate as 'true' drivers/scsi/sym53c416.c:636: warning: the address of 'sym53c416_2' will always evaluate as 'true' drivers/scsi/sym53c416.c:642: warning: the address of 'sym53c416_3' will always evaluate as 'true' So fix this longstanding bug to keep gcc quiet.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | Since the sg chaining patches went in, our current value of 255 for SG_ALL excites chaining on some drivers which cannot support it (and would thus oops). Redefine SG_ALL to mean no sg table size preference, but use the single allocation (non chained) limit. This also helps for drivers that use it to size an internal table. We'll do an opt in system later where truly chaining supporting drivers can define their sg_tablesize to be anything up to SCSI_MAX_SG_CHAIN_ELEMENTS.

| * [SCSI] MegaRAID driver management char device moved to miscThomas Horsten2008-02-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The MegaRAID driver's common management module (megaraid_mm.c) creates a char device used by the management tool "megarc" from LSI Logic (and possibly other management tools). In 2.6 with udev, this device doesn't get created because it is not registered in sysfs. I first fixed this by registering a class "megaraid_mm", but realized that this should probably be moved to misc devices, instead of taking up a char major. This is because only 1 device is used, even if there are multiple adapters - the minor is never used (the adapter info is in the ioctl block sent to the driver, not detected based on the minor number as one might think). So it is a complete waste to have an entire major taken by this. So it now uses a misc device which I named "megadev0" (the name that megarc expects), and has a dynamic minor (previoulsy a dynamic major was used). I have tested this on my own system with the megarc tool, and it works just as fine as before (only now the device gets created correctly by udev).

| * [SCSI] advansys: fix overrun_buf aligned bugFUJITA Tomonori2008-02-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | struct asc_dvc_var needs overrun buffer to be placed on an 8 byte boundary. advansys defines struct asc_dvc_var: struct asc_dvc_var { ... uchar overrun_buf[ASC_OVERRUN_BSIZE] __aligned(8); The problem is that struct asc_dvc_var is placed on shost->hostdata. So if the hostdata is not on an 8 byte boundary, the advansys crashes. The hostdata is placed on a sizeof(unsigned long) boundary so the 8 byte boundary is not garanteed with x86_32. With 2.6.23 and 2.6.24, the hostdata is on an 8 byte boundary by chance, but with the current git, it's not. This patch removes overrun_buf static array and use kzalloc.

* | Linux Kernel Markers: create modpost fileMathieu Desnoyers2008-02-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* | Linux Kernel Markers: support multiple probesMathieu Desnoyers2008-02-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
