When building from an arbitrary commit in the git tree it's useful
for the resulting packages to be uniquely identifiable. Therefore,
the build system has been updated to detect if your compiling in
git tree.
If you are building in a git tree, and there are commits after the
last annotated tag. Then the <id>-<hash> component of 'git describe'
will be used to overwrite the 'Release:' field in the META file.
The only tricky part is that to ensure the 'make dist' tarball is
built using the correct release. A dist-hook was added to the top
level make file to rewrite the META file using the correct release.

Refresh the existing RPM packaging to conform to the 'Fedora
Packaging Guidelines'. This includes adopting the kmods2
packaging standard which is used fod kmods distributed by
rpmfusion for Fedora/RHEL.
http://fedoraproject.org/wiki/Packaging:Guidelineshttp://rpmfusion.org/Packaging/KernelModules/Kmods2
While the spec files have been entirely rewritten from a
user perspective the only major changes are:
* The Fedora packages now have a build dependency on the
rpmfusion repositories. The generic kmod packages also
have a new dependency on kmodtool-1.22 but it is bundled
with the source rpm so no additional packages are needed.
* The kernel binary module packages have been renamed from
spl-modules-* to kmod-spl-* as specificed by kmods2.
* The is now a common kmod-spl-devel-* package in addition
to the per-kernel devel packages. The common package
contains the development headers while the per-kernel
package contains kernel specific build products.

Therefore, we include 'linux/fs.h' which in turn includes the

In the upstream kernel the FALLOC_FL_PUNCH_HOLE #define was
introduced after the fallocate() function was moved from the
inode_operations to the file_operations structure. Therefore,
the SPL code assumed that if FALLOC_FL_PUNCH_HOLE was defined
it was safe to use f_ops->fallocate().
Unfortunately, the RHEL6.4 kernel has only backported the

This also allows us to drop three existing autoconf tests.

The kern_path_parent() function was removed from Linux 3.6 because
it was observed that all the callers just want the parent dentry.
The simpler kern_path_locked() function replaces kern_path_parent()
and does the lookup while holding the ->i_mutex lock.
This is good news for the vn implementation because it removes the
need for us to handle the locking. However, it makes it harder to
implement a single readable vn_remove()/vn_rename() function which
is usually what we prefer.
Therefore, we implement a new version of vn_remove()/vn_rename()
for Linux 3.6 and newer kernels. This allows us to leave the
existing working implementation untouched, and to add a simpler
version for newer kernels.
Long term I would very much like to see all of the vn code removed
since what this code enabled is generally frowned upon in the kernel.
But that can't happen util we either abondon the zpool.cache file
or implement alternate infrastructure to update is correctly in

This adds an interface to "punch holes" (deallocate space) in VFS
files. The interface is identical to the Solaris VOP_SPACE interface.
This interface is necessary for TRIM support on file vdevs.
This is implemented using Linux fallocate(FALLOC_FL_PUNCH_HOLE), which
was introduced in 2.6.38. For a brief time before 2.6.38 this was done
using the truncate_range inode operation, which was quickly deprecated.
This patch only supports FALLOC_FL_PUNCH_HOLE.
This adds support for the truncate_range() inode operation to
VOP_SPACE() for file hole punching. This API is deprecated and removed
in 3.5, so it's only useful for old kernels.
On tmpfs, the truncate_range() inode operation translates to
shmem_truncate_range(). Unfortunately, this function expects the end
offset to be inclusive and aligned to the end of a page. If it is not,
the kernel will stop with a BUG_ON().
This patch fixes the issue by adapting to the constraints set forth by
shmem_truncate_range().

This patch adds a new autoconf function: SPL_LINUX_TRY_COMPILE_SYMBOL.
This new function does the following:
- Call LINUX_TRY_COMPILE with the specified parameters.
- If unsuccessful, return false.
- If successful and we're configuring with --enable-linux-builtin,
return true.
- Else, call CHECK_SYMBOL_EXPORT with the specified parameters and
return the result.
All calls to CHECK_SYMBOL_EXPORT are converted to
LINUX_TRY_COMPILE_SYMBOL so that the tests work even when configuring
for builtin on a kernel which doesn't have loadable module support, or
hasn't been built yet.
The only exception are:
- AC_GET_VMALLOC_INFO, because we don't even have a public header to
include in the test case, but that's okay considering this symbol can
be ignored just fine.
- SPL_AC_DEVICE_CREATE, which is legacy API for 2.6.18 kernels. Since
kernels this old are no longer supported it should arguably just be
removed entirely from the build system.
Note that we're also checking for the correct prototype with an actual
call, which was not the case with CHECK_SYMBOL_EXPORT. However, for
"complicated" test cases like with multiple symbol versions (e.g.
vfs_fsync), we stick with the original behavior and only check for the
function's existence.

Issue zfsonlinux/zfs#851
Currently, when building a test case, we're compiling an entire Linux
module from beginning to end. This includes the MODPOST stage, which
generates a "conftest.mod.c" file with some boilerplate module
declaration code.
This poses a problem when configuring for built-in on kernels which have
loadable module support disabled. In this case conftest.mod.c is
referencing disabled code, resulting in a compilation failure, thus
breaking the tests.
This patch fixes the issue by faking the modpost stage when the
--enable-linux-builtin option is provided. It does so by forcing the
modpost command to be /bin/true, and using an empty conftest.mod.c file.
The test module still compiles fine, although the result isn't loadable,
but we don't really care at this point.
Note it is important to preserve the modpost stage when building out of
tree. This allows for the posibility of configure checks to leverage
this phase to identify GPL-only symbols.

Until now the notion of an internal debug logging infrastructure
was conflated with enabling ASSERT()s. This patch clarifies things
by cleanly breaking the two subsystem apart. The result of this
is the following behavior.
--enable-debug - Enable/disable code wrapped in ASSERT()s.
--disable-debug ASSERT()s are used to check invariants and
are never required for correct operation.
They are disabled by default because they
may impact performance.
--enable-debug-log - Enable/disable the debug log infrastructure.
--disable-debug-log This infrastructure allows the spl code and
its consumer to log messages to an in-kernel
log. The granularity of the logging can be
controlled by a debug mask. By default the
mask disables most debug messages resulting
in a negligible performance impact. Because
of this the debug log is enabled by default.
