  proc: remove write-only variable in proc_pident_lookup()
  proc: fix sparse warning
  proc: add /proc/*/stack

  proc: remove useless WARN_ONs
  proc: stop using BKL

zero i_uid/i_gid on inode allocation

2009-01-05T16:54:28+00:00

... and don't bother in callers.  Don't bother with zeroing i_blocks,
while we are at it - it's already been zeroed.

i_mode is not worth the effort; it has no common default value.

proc: add /proc/*/stack

2009-01-05T09:27:44+00:00

/proc/*/stack adds the ability to query a task's stack trace. It is more
useful than /proc/*/wchan as it provides full stack trace instead of single
depth. Example output:

	$ cat /proc/self/stack
	[] save_stack_trace_tsk+0x17/0x35
	[] proc_pid_stack+0x4a/0x76
	[] proc_single_show+0x4a/0x5e
	[] seq_read+0xf3/0x29f
	[] vfs_read+0x6d/0x91
	[] sys_read+0x3b/0x60
	[] syscall_call+0x7/0xb
	[] 0xffffffff

[add save_stack_trace_tsk() on mips, ACK Ralf --adobriyan]

proc: remove '##' usage

2009-01-05T09:27:44+00:00

Inability to jump to /proc/*/foo handlers with ctags is annoying.

NULL "struct inode *" means VFS passed NULL inode to ->open.

sched: fix warning in fs/proc/base.c

2008-12-22T06:41:06+00:00

Stephen Rothwell reported this new (harmless) build warning on platforms that
define u64 to long:

 fs/proc/base.c: In function 'proc_pid_schedstat':
 fs/proc/base.c:352: warning: format '%llu' expects type 'long long unsigned int', but argument 3 has type 'u64'

asm-generic/int-l64.h platforms strike again: that file should be eliminated.

Fix it by casting the parameters to long long.
