2013-05-01proc: Move non-public stuff from linux/proc_fs.h to fs/proc/internal.hDavid Howells
Move non-public declarations and definitions from linux/proc_fs.h to fs/proc/internal.h. Signed-off-by: David Howells <dhowells@redhat.com> Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
2013-05-01proc: Make the PROC_I() and PDE() macros internal to procfsDavid Howells
Make the PROC_I() and PDE() macros internal to procfs. This means making PDE_DATA() out of line. This could be made more optimal by storing PDE()->data into inode->i_private. Also provide a __PDE_DATA() that is inline and internal to procfs. Signed-off-by: David Howells <dhowells@redhat.com> Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
2013-05-01proc: Supply a function to remove a proc entry by PDEDavid Howells
Supply a function (proc_remove()) to remove a proc entry (and any subtree rooted there) by proc_dir_entry pointer rather than by name and (optionally) root dir entry pointer. This allows us to eliminate all remaining pde->name accesses outside of procfs.

2013-05-01drm: proc: Use minor->index to label things, not PDE->nameDavid Howells
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.

2013-05-01proc: Supply an accessor for getting the data from a PDE's parentDavid Howells
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).

2013-04-09procfs: new helper - PDE_DATA(inode)Al Viro
The only part of proc_dir_entry the code outside of fs/proc really cares about is PDE(inode)->data. Provide a helper for that; static inline for now, eventually will be moved to fs/proc, along with the knowledge of struct proc_dir_entry layout. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>

Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
2013-04-09new helper: single_open_size()Al Viro
Same as single_open(), but preallocates the buffer of given size. Doesn't make any sense for sizes up to PAGE_SIZE and doesn't make sense if output of show() exceeds PAGE_SIZE only rarely - seq_read() will take care of growing the buffer and redoing show(). If you _know_ that it will be large, it might make more sense to look into saner iterator, rather than go with single-shot one. If that's impossible, single_open_size() might be for you. Again, don't use that without a good reason; occasionally that's really the best way to go, but very often there are better solutions. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>

2013-04-09scsi: saner replacements for ->proc_info()Al Viro
It's still an obsolete interface; don't introduce those in new drivers. However, it's saner than the ->proc_info() and commits after this one will convert the existing ->proc_info() users to it. The read side is ->show_info(seq_file *, struct Scsi_Host *); use seq_... for generating contents. The write side is ->write_info(struct Scsi_Host *, char *, int). Again, this is driven by procfs needs; we are going to kill ->write_proc() and ->read_proc() and this is the main obstacle to burying that piece of shit.

2013-04-09pipe: take allocation and freeing of pipe_inode_info out of ->i_mutexAl Viro
* 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>

Also from Eric Dumazet. 16) Fix use after free in VLANs, from Cong Wang. 17) Fix TCP slow start retransmit storms after SACK reneging, from Yuchung Cheng. 18) Unix socket release should mark a socket dead before NULL'ing out sock->sk, otherwise we can race.

2013-03-22mm: zone_end_pfn is too smallRuss Anderson
Booting with 32 TBytes memory hits BUG at mm/page_alloc.c:552! (output below). The key hint is "page 4294967296 outside zone". 4294967296 = 0x100000000 (bit 32 is set). The problem is in include/linux/mmzone.h: 530 static inline unsigned zone_end_pfn(const struct zone *zone) 531 { 532 return zone->zone_start_pfn + zone->spanned_pages; 533 } zone_end_pfn is "unsigned" (32 bits). Changing it to "unsigned long" (64 bits) fixes the problem. zone_end_pfn() was added recently in commit 108bcc96ef70 ("mm: add & use zone_end_pfn() and zone_spans_pfn()") Output from the failure.

2013-03-22printk: Provide a wake_up_klogd() off-caseFrederic Weisbecker
wake_up_klogd() is useless when CONFIG_PRINTK=n because neither printk() nor printk_sched() are in use and there are actually no waiter on log_wait waitqueue. It should be a stub in this case for users like bust_spinlocks(). Otherwise this results in this warning when CONFIG_PRINTK=n and CONFIG_IRQ_WORK=n: kernel/built-in.o In function `wake_up_klogd': (.text.wake_up_klogd+0xb4): undefined reference to `irq_work_queue' To fix this, provide an off-case for wake_up_klogd() when CONFIG_PRINTK=n. There is much more from console_unlock() and other console related code in printk.c that should be moved under CONFIG_PRINTK. But for now, focus on a minimal fix as we passed the merged window already.
