Found by Simon Trimmer <simon@veritas.com>: shmem_file_write failure path duplicates kunmap, causing oops holding kmap_lock.

Trivial: vfs_link in 2.5 checks S_ISDIR first, shmem_link need not repeat it, but test crept back in at some stage.

Martin Schwidefsky <schwidefsky@de.ibm.com> reported "Bug with shared memory" to LKML 14 May: hang due to schedule in truncate_list_pages called from .... shm_destroy holding shm_lock spinlock. shm_destroy needs that lock for shm_rmid, but it can be safely unlocked once link from id to shp has been removed.

Here is a quick fix. I would like to synchronize with the irq handler changes as well. Becouse right now I know that preemption is killing the disk subsystem when moving data between disks using different request queues... In esp. It get's me in to do_request() with a queue in unplugged state. (Not everything is my fault, after all :-).

- init thread needs to have preempt_count of 1 until sched_init(). (William Lee Irwin III) - clean up the irq-mask macros. (Linus) - add barrier() to irq_enter() and irq_exit(). (based on Oleg Nesterov's comment.) - move the irqs-off check into preempt_schedule() and remove CONFIG_DEBUG_IRQ_SCHEDULE. - remove spin_unlock_no_resched() and comment the affected places more agressively. - slab.c needs to spin_unlock_no_resched(), instead of spin_unlock(). (It also has to check for preemption in the right spot.) This should fix the memory corruption. - irq_exit() needs to run softirqs if interrupts not active - in the previous patch it ran them when preempt_count() was 0, which is incorrect. - spinlock macros are updated to enable preemption after enabling interrupts. Besides avoiding false positive warnings, this also - fork.c has to call scheduler_tick() with preemption disabled - otherwise scheduler_tick()'s spin_unlock can preempt! - irqs_disabled() macro introduced. - [ all other local_irq_enable() or sti instances conditional on CONFIG_DEBUG_IRQ_SCHEDULE are to fix false positive warnings. ] - fix buggy in_softirq(). Fortunately the bug made the test broader, which didnt result in algorithmical breakage, just suboptimal performance. - move do_softirq() processing into irq_exit() => this also fixes the softirq processing bugs present in apic.c IRQ handlers that did not test for softirqs after irq_exit(). - simplify local_bh_enable().

M68k VT updates: - Include <linux/vt_kern.h> instead of copying the kd_mksound() prototype - Lots of stuff depends on CONFIG_VT: o SYSRQ_KEY o kd_mksound() o mach_keyb_init() o mach_kbdrate() o mach_kbd_leds() o mach_kbd_translate() o mach_sysrq_xlate() o Atari keyboard and joystick drivers - There's no need to provide dummy routines for kbd{rate,_leds}() - dummy_con depends on CONFIG_DUMMY_CONSOLE
