Remove the "#ifdef __KERNEL__" tests from unexported header files in
linux/include whose entire contents are wrapped in that preprocessor
test.

[This has four scalps already. Thomas Molina has agreed
to track things as they are identified ]
Infrastructure to detect sleep-inside-spinlock bugs. Really only
useful if compiled with CONFIG_PREEMPT=y. It prints out a whiny
message and a stack backtrace if someone calls a function which might
sleep from within an atomic region.
This patch generates a storm of output at boot, due to
drivers/ide/ide-probe.c:init_irq() calling lots of things which it
shouldn't under ide_lock.
It'll find other bugs too.

generic spinlock implementation for downgrade_write().
|
|
Here's a patch from Christoph Hellwig and myself to supply write->read
semaphore downgrade, and also from Brian Watson to supply trylock for rwsems.
|
|
- Al Viro: fs cleanups
- David Miller: sparc semaphores
- Christoph Hellwig: VxFS update
- Asit Mallick: set machine check bit with set_in_cr4
- Richard Henderson: fix alpha pci_controller_num(), sg_fill, SRM poweroff.
- Johannes Erdfelt: USB updates
- Cort Dougan: bitkeeper Id's on the ppc side
- Matt Chapman: NFS file locking SMP lock fix
- Alan Cox: further merging
|
|
- Johannes Erdfelt: USB updates
- David Howells: more rw-sem stuff
- David Miller: network callback cleanups and fixes
- Jan Harkes: make Coda use the proper VFS layer interfaces, so that it can use
"non-traditional-unix" filesystems without inode numbers for backing store.
|
|
- Chris Mason: daemonize reiserfs commit thread
- Alan Cox: syncup (AFFS might even work, and official VIA workarounds)
- Jeff Garzik: network driver updates
- Paul Mackerras: PPP update
- David Howells: more rw-sem cleanups, updates. Slowly getting somewhere.
|
|
- Mike Phillips: olympic driver update
- Alan Cox: continued resyncing (lots of small stuff, big NTFS merge from Anton)
- Martin Dalecki: cleanup (remove unused and unnecessary get_hardblocksize)
- Chris Mason: fix potential reiserfs journal overflow
- Jeff Garzik: network driver updates
- David Miller: sparc fixes, some network cleanups
|
|
- David Miller: sparc rw semaphores moved over
- Alan Cox: yet more resyncs
- NIIBE Yutaka: Super-H driver update
- David Howells: more rw-sem cleanups, updates
- USB updates
- Al Viro: filesystem init cleanup
|
|
- Hui-Fen Hsu: sis900 driver update
- NIIBE Yutaka: Super-H update
- Alan Cox: more resyncs (ARM down, but more to go)
- David Miller: network zerocopy, Sparc sync, qlogic,FC fix, etc.
- David Miller/me: get rid of various drivers hacks to do mmap
alignment behind the back of the VM layer. Create a real
protocol for it.
