[PATCH] PR_GET_DUMPABLE returns incorrect info
2.6.13 incorporated Alan Cox's patch for /proc/sys/fs/suid_dumpable (one version of this patch can be found here http://marc.theaimsgroup.com/?l=linux-kernel&m=109647550421014&w=2 ). This patch also made corresponding changes in kernel/sys.c to change the prctl() PR_SET_DUMPABLE operation so that the permitted range of 'arg2' was modified from 0..1 to 0..2. However, a corresponding change was not made for PR_GET_DUMPABLE: if the dumpable flag is non-zero, then PR_GET_DUMPABLE always returns 1, so that the caller can't determine the true setting of this flag.
