The patchset is meant to be pretty stable, not so much a testing ground. Main differences from mainline are: 1. Better performance & resource consumption, particularly on larger machines. 2. Diagnosis tools (kgdb, early_printk, etc). 3. Kexec support. 4. ivtv drivers I'd be very interested in feedback from anyone willing to test on any platform, however large or small. ftp://ftp.kernel.org/pub/linux/kernel/people/mbligh/2.6.5/patch-2.6.5-mjb2.bz2 Since the last release (~ = changed, + = added, - = dropped) Notes: ----------------------------------------------------------------------- Now in Linus' tree: - 4k_stacks Arjan / Dave H / bcrl Provide an option to use 4k kernel stacks instead of 8k - jbd_journal_speedup Andrew Morton ext3 fs speedup Dropped: New: + move_page_tables Hugh Dickins Change move_page_tables from int to unsigned long + sysfs_d_fsdata_race_fix_2 Maneesh Soni + sysfs_symlinks_fix Maneesh Soni + kobject_set_name_cleanup_01 Maneesh Soni + sysfs_rename_dir_cleanup Maneesh Soni ~ sysfs_backing_store1 Maneesh Soni ~ sysfs_backing_store2 Maneesh Soni ~ sysfs_backing_store3 Maneesh Soni ~ sysfs_backing_store4 Maneesh Soni ~ sysfs_backing_store5 Maneesh Soni ~ sysfs_backing_store6 Maneesh Soni Make sysfs more efficient in its usage of lowmem + ia64_rmap_build_fix Hugh Dickins + unmap_nonlinear Hugh Dickins + slab-panic Hugh Dickins + remove_pte_chains Hugh Dickins + add_anonmm_rmap Hugh Dickins + mremap_moves Hugh Dickins + pgtable_remove_rmap Hugh Dickins + include_asm_deletions Hugh Dickins + i_shared_lock Martin J.
