dtlk: off by one in {read,write}_tts()

2009-06-19T23:46:06+00:00

With a postfix increment retries is incremented beyond DTLK_MAX_RETRIES so
the error message is not displayed correctly.

Add a bunch of cycle_kernel_lock() calls

2008-06-20T20:05:53+00:00

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.

Add "no BKL needed" comments to several drivers

2008-06-20T20:05:50+00:00

This documents the fact that somebody looked at the relevant open()
functions and concluded that, due to their trivial nature, no locking was
needed.

dtlk: fix error checks in module_init()

2007-05-08T18:15:09+00:00

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.

header cleaning: don't include smp_lock.h when not used

2007-05-08T18:15:07+00:00

Remove includes of  where it is not used/needed.
Suggested by Al Viro.

Builds cleanly on x86_64, i386, alpha, ia64, powerpc, sparc,
sparc64, and arm (all 59 defconfigs).

[PATCH] Char: timers cleanup

2007-02-12T17:48:30+00:00

- 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.

[PATCH] make more file_operation structs static

2006-07-03T22:26:59+00:00

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..
