procfs: Convert /proc/pid/fdinfo/ handling routines to seq-file v2 · ddd3e077

Cyrill Gorcunov authored Aug 26, 2012

This patch converts /proc/pid/fdinfo/ handling routines to seq-file which
is needed to extend seq operations and plug in auxiliary fdinfo provides
from subsystems like eventfd/eventpoll/fsnotify.

Note the proc_fd_link no longer call for proc_fd_info, simply because
the guts of proc_fd_info() got merged into ->show() of that seq_file

procfs: Move /proc/pid/fd[info] handling code to fd.[ch] · faf60af1

Cyrill Gorcunov authored Aug 23, 2012

This patch prepares the ground for further extension of
/proc/pid/fd[info] handling code by moving fdinfo handling
code into fs/proc/fd.c.

I think such move makes both fs/proc/base.c and fs/proc/fd.c
easier to read.

new helper: daemonize_descriptors() · 864bdb3b

result we simplify the locking rules for ->files - we

new helper: iterate_fd() · c3c073f8

iterates through the opened files in given descriptor table,
calling a supplied function; we stop once non-zero is returned.
Callback gets struct file *, descriptor number and const void *
argument passed to iterator.  It is called with files->file_lock
held, so it is not allowed to block.

tty_io, netprio_cgroup and selinux flush_unauthorized_files()
converted to its use.
