Hi,

Inside linux kernel, is there anyway to differentiate whether a file is an
executable (i.e. "x" bit is on) or a data file "r or w" bit is on or both
given the inode that points to the file?

I've noticed this function "int permission(struct inode*, int mask)" in
namei.c.  However, when I pass in mingetty's inode and MAY_EXEC as the
mask into the permission() function, it returned 0.  Anyone knows why or
can suggest an alternative way to accomplish this?

Thanks a lot.
