Thanks, but, the 1st part of the patch with the corrections to the table
need to go in as well, otherwise there's a mismatch between what the
table says and what the code does: exe is a link:procfs_readlink(); emul
is a reg. file:procfs_doemul():

        { DT_LNK, N("emul"),    PFSemul,        NULL },
        { DT_REG, N("exe"),     PFSexe,         procfs_validfile },

$ ls -l /proc/self/emul /proc/self/exe
-r--r--r--  1 rvp   rvp    6 Jan 14 20:23 /proc/self/emul
lr-xr-xr-x  1 root  wheel  7 Jan 14 20:23 /proc/self/exe -> /bin/ls

$ ./a.out /proc/self		# print d_type vs. st_mode mismatches
DT_LNK: S_ISREG emul
DT_REG: S_ISLNK exe
