A question of system call chown().

firedragon

Hi,all,
I know that when the owner or group of an executable file are changed by a nonsuper-user, the S_ISUID and S_ISGID mode bits are cleared. In case of a nongroup-executable file, the S_ISGID bit indicates mandatory locking, and is not cleared by a chown(). But POSIX does not specify whether this also happen when root does the chown. My question is what is the behaviour of ARM linux when root does the chown?

Regards
