kernel/ksysfs.c: expose file_caps_enabled in sysfs A kernel booted with no_file_caps allows to install fscaps on a binary but doesn't actually honor the fscaps when running the binary. Userspace currently has no sane way to determine whether installing fscaps actually has any effect. Since parsing /proc/cmdline is fragile this patch exposes the current setting (1 or 0) via /sys/kernel/fscaps Signed-off-by: Ludwig Nussel <ludwig.nussel@suse.de> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
