Linus Torvalds 95f4efb2d7 selinux: simplify and clean up inode_has_perm() ... This is a rather hot function that is called with a potentially NULL "struct common_audit_data" pointer argument. And in that case it has to provide and initialize its own dummy common_audit_data structure. However, all the _common_ cases already pass it a real audit-data structure, so that uncommon NULL case not only creates a silly run-time test, more importantly it causes that function to have a big stack frame for the dummy variable that isn't even used in the common case! So get rid of that stupid run-time behavior, and make the (few) functions that currently call with a NULL pointer just call a new helper function instead (naturally called inode_has_perm_noapd(), since it has no adp argument). This makes the run-time test be a static code generation issue instead, and allows for a much denser stack since none of the common callers need the dummy structure. And a denser stack not only means less stack space usage, it means better cache behavior. So we have a win-win-win from this simplification: less code executed, smaller stack footprint, and better cache behavior. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>		14 years ago
