* : Tag spl-0.4.4
* : Added SLES10 support. This includes all compatibility
changes to support 2.6.16 based kernels and the required
build system improvements.
* : Build System changes for SLES10:
- Exclude -obj when detecting installed kernel source.
- Detect -obj directory for out of tree kernel builds.
- Allow kernel build system to set CC to ensure -m64 is set properly.
This is an issue on 64-bit SLES systems which by default always
build 32-bit binaries (unlike RHEL/Fedora which default to 64-bit)
* : Configure Checks added for SLES10:
- div64_64() renamed to div64_u64() as of 2.6.26.
- global_page_state() fuction was introduced in 2.6.18 kernels.
The earlier 2.6.16 based SLES10 must not try and use it,
thankfully get_zone_counts() is still available.
- monotonic_clock() is unavailable __gethrtime() must perform the
HZ division as an 'unsigned long long' because the SPL only
implements __udivdi3(), and not __divdi3() for 'long long'
division on 32-bit arches.
- mutex_lock_nested() was introduced as part of the mutex
validator in 2.6.18, when it is unavailable it is safe to
fallback to using a plain mutex_lock().
- SLES specific API change to vfs_unlink() and vfs_rename() which
added a 'struct vfsmount *' argument. This was for something
called the linux-security-module, but it appears that it was
never adopted upstream.
- spl_device_create() correctly mapped to class_device_create()
for 2.6.13 to 2.6.17 based kernels, this is the preferred API.
- Prior to 2.6.17 there were no *_pgdat helper functions in
mm/mmzone.c. Instead for_each_zone() operated directly on
pgdat_list which may or may not have been exported depending on
how your kernel was compiled. A configure check was added to
determine if you have the helpers or not, and if the needed
symbols are exported. If they are not exported then they are
dynamically aquired at runtime by kallsyms_lookup_name().
* : Packaging changes for SLES10
- Properly honor --prefix in build system and rpm spec file.
- Add '--define require_kdir' to spec file to support building
rpms against kernel sources installed in non-default locations.
- Add '--define require_kobj' to spec file to support building
rpms against kernel object installed in non-default locations.
- Stop suppressing errors in autogen.sh script.
- Improved logic to detect missing kernel objects when they are
not located with the source. This is the common case for SLES
as well as in-tree chaos kernel builds and is done to simply
support for multiple arches.
- Moved spl-devel build products to /usr/src/spl-<version>, a
spl symlink is created to reference the last installed version.
- Allow checking for exported symbols in both Module.symvers
and Module.symvers. My stock SLES kernel ships an objects
directory with Module.symvers, yet produces a Module.symvers
in the local build directory.
* : Added powerpc64 support.
- Enable builds for powerpc64 ISA type.
- Add DIV_ROUND_UP and roundup macros if unavailable.
- Cast 64-bit values for %lld format string to (long long) to
quiet compile warning.
* module/splat/splat-ctl.c: Proper ioctl() 32/64-bit binary
compatibility. We need to ensure the ioctl data itself is always
packed the same for 32/64-bit binaries. Additionally, the correct
thing to do is encode this size in bytes as part of the command
using _IOC_SIZE().
* modules/spl/spl-kmem.c: Fixed a long standing bug in the debug
tracing. The tcd_for_each() macro expected a NULL to terminate
the trace_data[i] array but this was only ever true due to luck.
All trace_data[] iterators are now properly capped by TCD_TYPE_MAX.
* modules/spl/spl-kmem.c: To simplify debugging all symbols aquired
dynamically using spl_kallsyms_lookup_name() are initially poisoned
with SYMBOL_POISON.
