[PATCH] Copy i_flags to ocfs2 inode flags on write
Propagate flags such as S_APPEND, S_IMMUTABLE, etc. from i_flags into ocfs2-specific ip_attr. Hence, when someone sets these flags via a different interface than ioctl, they are stored correctly. Signed-off-by: Jan Kara <jack@suse.cz> Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>
