Subject: [PATCH 00/26] Eliminate create_proc_read_entry() [RFC]
Here is a series of patches to eliminate create_proc_read_entry(), replacing it
with proc_create() and proc_create_data() and the use of seq_file facilities.
This requires file_operations structs and open methods to be provided in most
cases, though single_open() and single_open_size() suffice for the actual
translation into the seq_file environment. I did try and reduce the number of
file_operations structs and open methods added by placing the show function
pointer into seq_file::private in some places.
Certain places (hostap most notably) required conversion of some files into
full seq_file iterators to handle the possibility that large lists might
overrun a single buffer full of data.
This reduces the size of the proc_dir_entry by the removal of the read_proc
pointer, plus the support mechanisms for these have been removed from the
procfs code.
These patches have been compile tested as best I can (apart from SH for which I
don't have a working compiler). No runtime testing has been done outside of
the core procfs code as I don't have the requisite hardware.
These patches can be seen here also:
