TMPFS Features

The kernel includes extended attributes (xattr) and POSIX ACL support for tmpfs.

TMPFS Extended Attributes (TMPFS_XATTR)

Enables extended attributes on tmpfs filesystems. This is required for Mountify support and other features that depend on extended attributes on tmpfs.

TMPFS POSIX ACLs (TMPFS_POSIX_ACL)

Enables POSIX Access Control Lists on tmpfs filesystems, allowing more fine-grained permission control on tmpfs-mounted files.

Build Integration

Both features are enabled via kernel configuration options (CONFIG_TMPFS_XATTR and CONFIG_TMPFS_POSIX_ACL) and are included in the builds by default when the corresponding feature flags are set.
