2010-08-11vfs: show unreachable paths in getcwd and procMiklos Szeredi
Prepend "(unreachable)" to path strings if the path is not reachable from the current root. Two places updated are - the return string from getcwd() - and symlinks under /proc/$PID. Other uses of d_path() are left unchanged (we know that some old software crashes if /proc/mounts is changed).

2010-08-11vfs: only add " (deleted)" where necessaryMiklos Szeredi
__d_path() has 4 callers: d_path() sys_getcwd() seq_path_root() tomoyo_realpath_from_path2() Of these the only one which needs the " (deleted)" ending is d_path(). sys_getcwd() checks for existence before calling __d_path(). seq_path_root() is used to show the mountpoint path in /proc/PID/mountinfo, which is always a positive. And tomoyo doesn't want the deleted ending. Create a helper "path_with_deleted()" as subsequent patches will need this in multiple places.

2010-08-11vfs: add prepend_path() helperMiklos Szeredi
Split off prepend_path() from __d_path(). This new helper takes an end-of-buffer pointer and buffer-length pointer just like the other prepend_* functions. Move the " (deleted)" postfix out to __d_path(). This patch doesn't change any functionality but paves the way for the following patches.

2010-08-11vfs: __d_path: dont prepend the name of the root dentryMiklos Szeredi
In the old times pseudo-filesystems set the name of theroot dentry to some prefix like "pipe:" and the name of the child dentry to "[123]" and relied on a hack in __d_path() to replace the preceding slash with the root's name to get "pipe:[123]". Then the d_dname() dentry operation was introduced which solved the same problem without having to pre-fill the name in each dentry. Currently the following pseudo filesystems exist in the kernel: perfmon mtd anon_inode bdev pipe socket Of these only perfmon, anon_inode, pipe and socket create sub-dentries, all of which have now been switched to using d_dname(). bdev and mtd only create inodes. This means that now the hack to overwrite the slash can be removed, so for unreachable paths (e.g. within a detached mount) the path string won't be polluted with garbage. For these cases a subsequent patch will add a prefix, indicating that the path is unreachable. Signed-off-by: Miklos Szeredi <mszeredi@suse.cz> Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
2010-08-11ia64: perfmon: add d_dname methodMiklos Szeredi

This patch fixes a race condition in two utility routines related to the removal/unlinking of urbs from an anchor. If two threads are concurrently accessing the same anchor, both could end up with the same urb - thinking they are the exclusive owner. Alan Stern pointed out a related issue in usb_unlink_anchored_urbs: "The URB isn't removed from the anchor until it completes (as a by-product of completion, in fact), which might not be for quite some time after the unlink call returns. In the meantime, the subroutine will keep trying to unlink it, over and over again."
