* procfs: Convert /proc/pid/fdinfo/ handling routines to seq-file v2Cyrill Gorcunov2012-09-261-48/+64
| | | | | | | | | | | 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 Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
* procfs: Move /proc/pid/fd[info] handling code to fd.[ch]Cyrill Gorcunov2012-09-265-387/+416
| | | | | | | | | | | | | | | | | | | | | | 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()Al Viro2012-09-263-3/+8
| | | | | | | | descriptor-related parts of daemonize, done right. As the result we simplify the locking rules for ->files - we hold task_lock in *all* cases when we modify ->files. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>

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.

* expose a low-level variant of fd_install() for binderAl Viro2012-09-263-13/+18
| | | | | | | | | | | | | | Similar situation to that of __alloc_fd(); do not use unless you really have to. You should not touch any descriptor table other than your own; it's a sure sign of a really bad API design. As with __alloc_fd(), you *must* use a first-class reference to struct files_struct; something obtained by get_files_struct(some task) (let alone direct task->files) will not do. It must be either current->files, or obtained by get_files_struct(current) by the owner of that sucker and given to you. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>

* don't bother with call_rcu() in put_files_struct()Al Viro2012-09-261-9/+5
| | | | | | | | | | | At that point nobody can see us anyway; everything that looks at files_fdtable(files) is separated from the guts of put_files_struct(files) - either since files is current->files or because we fetched it under task_lock() and hadn't dropped that yet, or because we'd bumped files->count while holding task_lock()...
