An open of /dev/ptmx,\nallocates the next pty index and the associated device shows up in the\ndevpts fs as /dev/pts/n.\n\nWih multiple instancs of devpts filesystem, during an open of /dev/ptmx\nwe would be unable to determine which instance of the devpts is being\naccessed.\n\nSo we move the \u0027ptmx\u0027 node into /dev/pts and use the inode of the \u0027ptmx\u0027\nnode to identify the superblock and hence the devpts instance. This patch\nadds ability for the kernel to internally create the [ptmx, c, 5:2] device\nwhen mounting devpts filesystem. Since the ptmx node in devpts is new and\nmay surprise some userspace scripts, the default permissions for the new\nnode is 0000.

To\n\t simplify patchset, fold the ptmx_dentry patch into this.\n\nChangelog[v4]:\n\t- Change default permissions of pts/ptmx node to 0000.\n\t- Move code for ptmxmode under #ifdef CONFIG_DEVPTS_MULTIPLE_INSTANCES.\n\nChangelog[v3]:\n\t- Rename ptmx_mode to ptmxmode (for consistency with \u0027newinstance\u0027)\n\nChangelog[v2]:\n\t- [H.
