e42270a19e reiserfs: Don't access the proc_dir_entry in r_open(), r_start() r_show() 
Don't access the proc_dir_entry in ReiserFS's r_open(), r_start() r_show()
procfs interface functions.

ReiserFS stores the ->show() method pointer in PDE->data and the super_block
pointer in PDE->parent->data.  This isn't changing.

Currently, ReiserFS passes the PDE pointer into seq_file::private from
r_open() so that r_start() and r_show() can then access it.  Instead, use
seq_open_private() to allocate a two-pointer struct that's passed through
seq_file::private and put the ->show() method and the sb pointers in there.

4a520d2769 proc: Supply an accessor for getting the data from a PDE's parent 
Supply an accessor function for getting the private data from the parent
proc_dir_entry struct of the proc_dir_entry struct associated with an inode.

ReiserFS, for instance, stores the super_block pointer in the proc directory
it makes for that super_block, and a pointer to the respective seq_file show
function in each of the proc files in that directory.

This allows a reduction in the number of file_operations structs, open
functions and seq_operations structs required.  The problem otherwise is that
each show function requires two pieces of data but only has storage for one
per PDE (and this has no release function).

c4558a26ff rtl8187se: Use a dir under /proc/net/r8180/ 
Create a dir under /proc/net/r8180/ named for the device and create that
device's files under there.  This means that there won't be a problem for
multiple devices in the system (if such is possible) and it means we don't
need to save the 'device directory' PDE any more as we can just do a proc
subtree removal.

5ba02e355d rtl8187se: Don't use create_proc_read_entry() 
Don't use create_proc_read_entry() as that is deprecated, but rather use
proc_create_data() and seq_file instead.  Whilst we're at it, reduce the
number of show functions where we can share them.

Question: Do any of the registers read by proc_get_registers() have side
effects upon reading?  If so, locking will be required.

0541f9d08a rtl8192u: Don't use create_proc_read_entry() 
Don't use create_proc_read_entry() as that is deprecated, but rather use
proc_create_data() and seq_file instead.  Whilst we're at it, reduce the
number of show functions where we can share them.

Note: proc_get_stats_ap() should probably use seq_file iteration rather than
list_for_each_entry().

Further note: There appears to be a lot of locking missing in this file to
defend against concurrent access by the driver doing normal operations.
Notably, ieee->network_list traversal and RWCAM/RCAMO command/response access.
Further, do any of the registers read have side effects upon reading?

1678ec00a6 mISDN: fix misdn_add_timer()/misdn_del_timer() race 
do add_timer() *before* unlocking dev->lock, or unpleasant things can
happen if misdn_del_timer() on another CPU finds the sucker, calls
del_timer_sync() (which does nothing, since we hadn't started the
timer yet) and frees it, just as we get around to add_timer()...

c08c464d6f mISDN: fix the races with timers going off just as they are deleted 
timer callback in timerdev.c both accesses struct mISDNtimer it's
called for *and* moves it to dev->expired.  We need del_timer_sync(),
or we risk kfree() freeing it right under dev_expire_timer() *and*
dev->expired getting corrupted.
