Initial commit. All spl source written up to this point wrapped in an initial reasonable autoconf style build system. This does not yet build but the configure system does appear to work properly and integrate with the kernel.

AC_CONFIG_HEADERS([spl_config.h])
Allow spl_config.h to be included by dependant packages We need dependent packages to be able to include spl_config.h so they can leverage the configure checks the SPL has done. This is important because several of the spl headers need the results of these checks to work properly. Unfortunately, the autoheader build product is always private to a particular build and defined certain common things. (PACKAGE, VERSION, etc). This prevents other packages which also use autoheader from being include because the definitions conflict. To avoid this problem the SPL build system leverage AH_BOTTOM to include a spl_unconfig.h at the botton of the autoheader build product. This custom include undefs all known shared symbols to prevent the confict. This does however mean that those definition are also not availble to the SPL package either. The SPL package therefore uses the equivilant SPL_META_* definitions.

2.6.27+ portability changes - Added SPL_AC_3ARGS_ON_EACH_CPU configure check to determine if the older 4 argument version of on_each_cpu() should be used or the new 3 argument version. The retry argument was dropped in the new API which was never used anyway. - Updated work queue compatibility wrappers. The old way this worked was to pass a data point when initialized the workqueue. The new API assumed the work item is embedding in a structure and we us container_of() to find that data pointer. - Updated skc->skc_flags to be an unsigned long which is now type checked in the bit operations. This silences the warnings. - Updated autogen products and splat tests accordingly

SPL_AC_3ARGS_ON_EACH_CPU
Linux VM Integration Cleanup Remove all instances of functions being reimplemented in the SPL. When the prototypes are available in the linux headers but the function address itself is not exported use kallsyms_lookup_name() to find the address. The function name itself can them become a define which calls a function pointer. This is preferable to reimplementing the function in the SPL because it ensures we get the correct version of the function for the running kernel. This is actually pretty safe because the prototype is defined in the headers so we know we are calling the function properly. This patch also includes a rhel5 kernel patch we exports the needed symbols so we don't need to use kallsyms_lookup_name(). There are autoconf checks to detect if the symbol is exported and if so to use it directly. We should add patches for stock upstream kernels as needed if for no other reason than so we can easily track which additional symbols we needed exported. Those patches can also be used by anyone willing to rebuild their kernel, but this should not be a requirement. The rhel5 version of the export-symbols patch has been applied to the chaos kernel. Additional fixes: 1) Implement vmem_size() function using get_vmalloc_info() 2) SPL_CHECK_SYMBOL_EXPORT macro updated to use $LINUX_OBJ instead of $LINUX because Module.symvers is a build product. When $LINUX_OBJ != $LINUX we will not properly detect exported symbols. 3) SPL_LINUX_COMPILE_IFELSE macro updated to add include2 and $LINUX/include search paths to allow proper compilation when the kernel target build directory is not the source directory.

SPL_AC_KALLSYMS_LOOKUP_NAME
SPL_AC_GET_VMALLOC_INFO
Linux VM integration / device special files Support added to provide reasonable values for the global Solaris VM variables: minfree, desfree, lotsfree, needfree. These values are set to the sum of their per-zone linux counterparts which should be close enough for Solaris consumers. When a non-GPL app links against the SPL we cannot use the udev interfaces, which means non of the device special files are created. Because of this I had added a poor mans udev which cause the SPL to invoke an upcall and create the basic devices when a minor is registered. When a minor is unregistered we use the vnode interface to unlink the special file.

Additional Linux VM integration Added support for Solaris swapfs_minfree, and swapfs_reserve tunables. In additional availrmem is now available and return a reasonable value which is reasonably analogous to the Solaris meaning. On linux we return the sun of free and inactive pages since these are all easily reclaimable. All tunables are available in /proc/sys/kernel/spl/vm/* and they may need a little adjusting once we observe the real behavior. Some of the defaults are mapped to similar linux counterparts, others are straight from the OpenSolaris defaults.

SPL_AC_GET_ZONE_COUNTS
FC10/i686 Compatibility Update (2.6.27.19-170.2.35.fc10.i686) In the interests of portability I have added a FC10/i686 box to my list of development platforms. The hope is this will allow me to keep current with upstream kernel API changes, and at the same time ensure I don't accidentally break x86 support. This patch resolves all remaining issues observed under that environment. 1) SPL_AC_ZONE_STAT_ITEM_FIA autoconf check added. As of 2.6.21 the kernel added a clean API for modules to get the global count for free, inactive, and active pages. The SPL attempts to detect if this API is available and directly map spl_global_page_state() to global_page_state(). If the full API is not available then spl_global_page_state() is implemented as a thin layer to get these values via get_zone_counts() if that symbol is available. 2) New kmem:vmem_size regression test added to validate correct vmem_size() functionality. The test case acquires the current global vmem state, allocates from the vmem region, then verifies the allocation is correctly reflected in the vmem_size() stats. 3) Change splat_kmem_cache_thread_test() to always use KMC_KMEM based memory. On x86 systems with limited virtual address space failures resulted due to exhaustig the address space. The tests really need to problem exhausting all memory on the system thus we need to use the physical address space. 4) Change kmem:slab_lock to cap it's memory usage at availrmem instead of using the native linux nr_free_pages(). This provides additional test coverage of the SPL Linux VM integration. 5) Change kmem:slab_overcommit to perform allocation of 256K instead of 1M. On x86 based systems it is not possible to create a kmem backed slab with entires of that size. To compensate for this the number of allocations performed in increased by 4x. 6) Additional autoconf documentation for proposed upstream API changes to make additional symbols available to modules. 7) Console error messages added when spl_kallsyms_lookup_name() fails to locate an expected symbol. This causes the module to fail to load and we need to know exactly which symbol was not available.

To build binary RPMs from the source RPM for your system simply run: rpmbuild --rebuild spl-x.y.z-1.src.rpm This will produce two binary RPMs with correct 'requires' dependencies for your kernel.
