ppc: Clean up rtas_flash driver somewhat
Clean up some of the problems with the rtas_flash driver:
(1) It shouldn't fiddle with the internals of the procfs filesystem (altering
pde->count).
(2) If pid namespaces are in effect, then you can get multiple inodes
connected to a single pde, thereby rendering the pde->count > 2 test
useless.
(3) The pde->count fudging doesn't work for forked, dup'd or cloned file
descriptors, so add static mutexes and use them to wrap access to the
driver through read, write and release methods.
(4) The driver can only handle one device, so allocate most of the data
previously attached to the pde->data as static variables instead (though
allocate the validation data buffer with kmalloc).
(5) We don't need to save the pde pointers as long as we have the filenames
available for removal.
(6) Don't try to multiplex what the update file read method does based on the
filename. Instead provide separate file ops and split the function.
Whilst we're at it, tabulate the procfile information and loop through it when
creating or destroying them rather than manually coding each one.

Things could theoretically be improved by storing the drm_minor pointer in the

that, so I don't see an easy way of doing it.

Don't access the proc_dir_entry in ReiserFS's r_open(), r_start() r_show()

ReiserFS stores the ->show() method pointer in PDE->data and the super_block

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.

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).

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

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?
