umode_t breakage in exported kernel headers

commit 0583fcc96bb117763c0fa74c123573c0112dec65 moved umode_t out of the 
exported headers space (via the arches' asm/types.h) and into __KERNEL__ 
specific linux/types.h.  this breaks the exported linux/ext2_fs.h 
ext2_mask_flags function which uses that type.  that func appears to be the 
only one exported that utilizes umode_t.

should ext2_mask_flags be updated to take a __kernel_mode_t as its first arg ?
