Jori Koolstra <jkoolstra@xs4all.nl> says: To get an operable version of an O_PATH file descriptor, it is possible to use openat(fd, ".", O_DIRECTORY) for directories, but other files currently require going through open("/proc/<pid>/fd/<nr>"), which depends on a functioning procfs. This patch adds the O_EMPTYPATH flag to openat(2)/openat2(2). If passed, LOOKUP_EMPTY is set at path resolution time. * patches from https://patch.msgid.link/20260424114611.1678641-1-jkoolstra@xs4all.nl: selftest: add tests for O_EMPTYPATH vfs: add O_EMPTYPATH to openat(2)/openat2(2) Link: https://patch.msgid.link/20260424114611.1678641-1-jkoolstra@xs4all.nl Signed-off-by: Christian Brauner <brauner@kernel.org>
