This improves + performance by removing the need for a global spinlock. + + * module/spl/spl-debug.c: Rebase cmn_err on vcmn_err. Handle the + case where the message contains a leading ! which means only send + it to syslog. And suppress warnings for messages which do not end + in a '\n'. + + * module/splat/splat-ctl.c: Update to use kobject_set_name() for + increased portability. + + * module/spl/spl-generic.c: Set cwd to '/' for the task during + module load for SPL dependent modules. Under Solaris this is + the expected behavior, on a Linux system your cwd remains set + to whatever the tasks cwd was when loading a module. + + * module/spl/spl-mutex.c: Reimplemented mutexs for improved + performance and cleaner integration with the Linux kernels built + in lock analyzer. As of 2.6.29 based kernels adaptive mutexs + are supported, for these newer kernels task_curr() does not need + to be exported. Finally, DEBUG_MUTEX support was dropped in + favor of more detailed kernel profiling which is now available. + + * module/spl/spl-rwlock.c: Reimplemented rwlocks for improved + performance and cleaner integration with the Linux kernels built + in lock analyzer. Additionally, the rwlock regression tests were + improved to help validate correctness. + + * spl-modules.spec.in: Various spec file tweaks for the supported + distros: RHEL5, RHEL6, SLES10, SLES11, Chaos4, Fedora 11. + 2009-08-04 Brian Behlendorf <[email protected]> * : Tag spl-0.4.5 |
