CONFIG_DEVPTS_MULTIPLE_INSTANCES: Support multiple instances of devpts

General informations

The Linux kernel configuration item CONFIG_DEVPTS_MULTIPLE_INSTANCES has multiple definitions:

Support multiple instances of devpts found in drivers/char/Kconfig

The configuration item CONFIG_DEVPTS_MULTIPLE_INSTANCES:

• prompt: Support multiple instances of devpts
• type: bool
• depends on: CONFIG_UNIX98_PTYS
• defined in drivers/char/Kconfig
• found in Linux kernels: 2.6.29–2.6.38

Help text

Enable support for multiple instances of devpts filesystem. If you want to have isolated PTY namespaces (eg: in containers), say Y here. Otherwise, say N. If enabled, each mount of devpts filesystem with the '-o newinstance' option will create an independent PTY namespace.
