- in mkdir: we already hold parent directory's semaphore (c.f. driverfs_create_dir) - in create: ditto (c.f. driverfs_create_file) - in unlink: ditto (c.f. driverfs_remove_file) and file's i_sem is taken in vfs_unlink - un lseek: take inode's i_sem (though I think we can replace this with a common lseek function...later)

- introduce new type of context-switch locking, this is a must-have for ia64 and sparc64. - load_balance() bug noticed by Scott Rhine and myself: scan the whole list to find imbalance number of tasks, not just the tail of the list. - sched_yield() fix: use current->array not rq->active.

Switch to set_current_state() and move before add_wait_queue(). Updated README from master HTML file. Fixed devfs entry leak in <devfs_readdir> when *readdir fails.

The patch below consolidates some duplicate code, reduces some indentation, and adds a freeing of a page in mem_read() that could be left unfreed, as far as I can see.

Sync_sbs tries to access the ->sb for the first rdev of an mddev. This can oops as the wrong arg is given to list_entry, and also if a define was faound to be failed, as failed devices have their ->sb removed. But that removal isn't necessary, so now an rdev will always have an ->sb.

Define container_of which cast from member to struct with some type checking. This is much like list_entry but is cearly for things other than lists. List_entry now uses container_of.

The old form of designated initializers are obsolete: we need to replace them with the ISO C forms before 2.6. Gcc has always supported both forms anyway.

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().

This is needed as long as we have the directory of symlinks in the bus subdir in driverfs to point to the unique interfaces.
