Clean up the pseries scanlog driver's use of procfs: (1) Don't need to save the proc_dir_entry pointer as we have the filename to remove with. (2) Save the scan log buffer pointer in a static variable (there is only one of it) and don't save it in the PDE (which doesn't have a destructor).

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.

Use remove_proc_subtree() rather than remove_proc_entry() to remove a minor-specific drm proc directory and all its children. Things could theoretically be improved by storing the drm_minor pointer in the minor-specific dir proc_dir_entry struct data and then scrapping the list of proc files - but that's shared with the debugfs interface where you can't do that, so I don't see an easy way of doing it.

Use minor->index to label things, not the name field from the proc_dir_entry of the /proc/dwm/<minor>/ directory. Also, use "%u" not "%d" to render the value and use a 12-byte buffer in which to render the integer, not a 16-byte buffer. The longest string an unsigned int can give you is 10 chars (4294967295) plus a NUL, so round up to 12 as the stack is likely to be 4- or 8-byte aligned. Signed-off-by:

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. Signed-off-by:

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). Signed-off-by:

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.

Add proc_mkdir_data() to allow procfs directories to be created that are annotated at the time of creation with private data rather than doing this post-creation. This means no access is then required to the proc_dir_entry struct to set this. Signed-off-by:
