headers: smp_lock.h redux

2009-07-12T19:22:34+00:00

* Remove smp_lock.h from files which don't need it (including some headers!)
* Add smp_lock.h to files which do need it
* Make smp_lock.h include conditional in hardirq.h
  It's needed only for one kernel_locked() usage which is under CONFIG_PREEMPT

  This will make hardirq.h inclusion cheaper for every PREEMPT=n config
  (which includes allmodconfig/allyesconfig, BTW)

Fix AUTOFS_DEV_IOCTL_REQUESTER_CMD

2009-04-21T03:01:15+00:00

Missing conversion from kernel to userland dev_t; this sucker
breaks as soon as we get sufficiently many autofs mounts for
new_encode_dev(s_dev) != s_dev.

Note: this is the minimal fix.

autofs4: cleanup expire code duplication

2009-04-01T15:59:23+00:00

A significant portion of the autofs_dev_ioctl_expire() and
autofs4_expire_multi() functions is duplicated code.  This patch cleans that
up.

autofs4: fix string validation check order

2009-01-06T23:59:23+00:00

In function validate_dev_ioctl() we check that the string we've been sent
is a valid path.  The function that does this check assumes the string is
NULL terminated but our NULL termination check isn't done until after this
call.  This patch changes the order of the check.

autofs4: make autofs type usage explicit

2009-01-06T23:59:23+00:00

- the type assigned at mount when no type is given is changed
  from 0 to AUTOFS_TYPE_INDIRECT. This was done because 0 and
  AUTOFS_TYPE_INDIRECT were being treated implicitly as the same
  type.

- previously, an offset mount had it's type set to
  AUTOFS_TYPE_DIRECT|AUTOFS_TYPE_OFFSET but the mount control
  re-implementation needs to be able distinguish all three types.
  So this was changed to make the type setting explicit.

- a type AUTOFS_TYPE_ANY was added for use by the re-implementation
  when checking if a given path is a mountpoint. It's not really a
  type as we use this to ask if a given path is a mountpoint in the
  autofs_dev_ioctl_ismountpoint() function.

- functions to set and test the autofs mount types have been added to
  improve readability and make the type usage explicit.

- the mount type is used from user space for the mount control
  re-implementtion so, for consistency, all the definitions have
  been moved to the user space include file include/linux/auto_fs4.h.

autofs4: fix var shadowed by local delaration

2009-01-06T23:59:23+00:00

A local definition of devid in autofs_dev_ioctl_ismountpoint() shadows
the fuction wide definition.
