Re: [PATCH 09/19] jfs: replace inode uid,gid,mode initialization with helper function

One minor nit though.  jfs maintains jfs_inode->mode2 which is a
superset of inode->i_mode.  Since inode_init_owner() may set S_ISGID,
the following change should also be made.  (I don't think these
duplicate bits in mode2 are really important, but we may as well be
consistent.)

diff -Nurp linux/fs/jfs/jfs_inode.c linux.new/fs/jfs/jfs_inode.c

 	}

+	jfs_inode->mode2 |= inode->i_mode;
 
 	inode->i_blocks = 0;
 	inode->i_mtime = inode->i_atime = inode->i_ctime = CURRENT_TIME;

Thanks,
Shaggy
