* i2o: use proc_remove_subtree()Al Viro2013-04-091-50/+1
| | | | Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
* silicom: bury bp_proc.cAl Viro2013-04-093-1330/+0
| | | | | | | | | It's a seriously rotten copy of parts of bp_mod.c; had been ifdefed out all along, lacks a bunch of declarations that would be needed if ifdef had been removed, all stuff in it is duplicated in bp_mod.c anyway... Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
* silicom: switch to create_proc_data(), clean procfs side of things upAl Viro2013-04-091-820/+379

* isp1362-hcd: don't reimplement proc_create_data()Al Viro2013-04-091-4/+1

* rtl8192u: don't play with reassigning ->proc_fops, just use proc_create()Al Viro2013-04-091-5/+1
| | | | Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
* dgrp procfs fixes, part 6: just use proc_create{,_data}Al Viro2013-04-093-65/+4
| | | | | | | | ->permission() of its own is a rudiment of sysctl imitation; normal procfs logics will do just fine here, no need to mess with ->proc_iops at all. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
* dgrp procfs fixes, part 5: per-node filesAl Viro2013-04-096-129/+45
| | | | | | | this "hooks" scheme is pointless - just make file_operations non-static and consolidate initialiazation bits. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
* dgrp procfs fixes, part 4: get rid of sysctl-like machineryAl Viro2013-04-092-270/+42
| | | | | | racy and very overblown... Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
* dgrp procfs fixes, part 3: kill dead codeAl Viro2013-04-091-63/+0

* dgrp procfs fixes, part 2Al Viro2013-04-091-4/+1
| | | | | | | All table entries either have non-NULL ->proc_file_fops or non-NULL child. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
* dgrp procfs fixes, part 1Al Viro2013-04-091-2/+1
| | | | | | | | proc_create() has shat upon fops argument when mode is S_IFDIR. Good thing, too, since fops passed to it is completely useless for any directory. Just use proc_mkdir(), damnit. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
* The rtl8192e procfs-based debug interface seems very brokenSean MacLennan2013-04-094-1041/+0
| | | | | | | | | The procfs debug code in rtl_debug.c is, ironically, very buggy: it lacks proper locking. Since the most useful part of the code (the stats) are available through more standard APIs, I think it is best to just delete the whole mess.

| | | | | | proc_mkdir() is there for purpose... Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
* procfs: switch /proc/self away from proc_dir_entryAl Viro2013-04-096-12/+56
| | | | | | | Just have it pinned in dcache all along and let procfs ->kill_sb() drop it before kill_anon_super(). Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>

* hysdn: stash pointer to card into proc_dir_entry->dataAl Viro2013-04-092-85/+18
| | | | | | | no need to search later - we know the card when we are creating procfs entries Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>

* get rid of the last free_pipe_info() callersAl Viro2013-04-093-15/+8
| | | | | | and rename __free_pipe_info() to free_pipe_info() Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
* get rid of alloc_pipe_info() argumentAl Viro2013-04-093-5/+5
| | | | | | not used anymore Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
* get rid of pipe->inodeAl Viro2013-04-094-8/+5
| | | | | | | | it's used only as a flag to distinguish normal pipes/FIFOs from the internal per-task one used by file-to-file splice. And pipe->files would work just as well for that purpose... Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
* introduce variants of pipe_lock/pipe_unlock for real pipes/FIFOsAl Viro2013-04-091-15/+25
| | | | | | | fs/pipe.c file_operations methods *know* that pipe is not an internal one; no need to check pipe->inode for those callers. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
* pipe: set file->private_data to ->i_pipeAl Viro2013-04-092-11/+10
| | | | | | simplify get_pipe_info(), while we are at it Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
* pipe: don't use ->i_mutexAl Viro2013-04-093-6/+7
| | | | | | | now it can be done - put mutex into pipe_inode_info, use it instead of ->i_mutex Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
* pipe: take allocation and freeing of pipe_inode_info out of ->i_mutexAl Viro2013-04-092-21/+53
| | | | | | | | | | | | | | | | | | * new field - pipe->files; number of struct file over that pipe (all sharing the same inode, of course); protected by inode->i_lock. * pipe_release() decrements pipe->files, clears inode->i_pipe when if the counter has reached 0 (all under ->i_lock) and, in that case, frees pipe after having done pipe_unlock() * fifo_open() starts with grabbing ->i_lock, and either bumps pipe->files if ->i_pipe was non-NULL or allocates a new pipe (dropping and regaining ->i_lock) and rechecks ->i_pipe; if it's still NULL, inserts new pipe there, otherwise bumps ->i_pipe->files and frees the one we'd allocated. At that point we know that ->i_pipe is non-NULL and won't go away, so we can do pipe_lock() on it and proceed as we used to. If we end up failing, decrement pipe->files and if it reaches 0 clear ->i_pipe and free the sucker after pipe_unlock(). Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
* pipe: preparation to new locking rulesAl Viro2013-04-091-23/+15
| | | | | | | | * use the fact that file_inode(file)->i_pipe doesn't change while the file is opened - no locks needed to access that. * switch to pipe_lock/pipe_unlock where it's easy to do Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
