All of the open() functions which don't need the BKL on their face may
still depend on its acquisition to serialize opens against driver
initialization. So make those functions acquire then release the BKL to be
on the safe side.Signed-off-by: Jonathan Corbet

This documents the fact that somebody looked at the relevant open()
functions and concluded that, due to their trivial nature, no locking was
needed.Signed-off-by: Jonathan Corbet

This patch fixes two things in module_init.
- fix register_chrdev() error check
Currently dtlk doesn't check register_chrdev() failure correctly.
register_chrdev() returns a errno on failure.- check probe failure
dtlk ignores probe failure and allows the module loading without
such device. I got "Trying to free nonexistent resource" message
by release_region() when unloading module without device.[akpm@linux-foundation.org: fix error code return]

- Use timer macros to set function and data members and to modify
expiration time.
- Use DEFINE_TIMER for global timers and do not init them at run-time in
these cases.
- del_timer_sync is common in most cases -- we want to wait for timer
function if it's still running.Signed-off-by: Jiri Slaby

Mark the static struct file_operations in drivers/char as const. Making
them const prevents accidental bugs, and moves them to the .rodata section
so that they no longer do any false sharing; in addition with the proper
debug option they are then protected against corruption..[akpm@osdl.org: build fix]

There were still a few comments left refering to verify_area, and two
functions, verify_area_skas & verify_area_tt that just wrap corresponding
access_ok_skas & access_ok_tt functions, just like verify_area does for
access_ok - deprecate those.There was also a few places that still used verify_area in commented-out
code, fix those up to use access_ok.After applying this one there should not be anything left but finally
removing verify_area completely, which will happen after a kernel release
or two.Signed-off-by: Jesper Juhl

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.Let it rip!
