- Add conditional VFS Giant locking to getdents_common() (linux ABIs),
ibcs2_getdents(), ibcs2_read(), ogetdirentries(), svr4_sys_getdents(), and svr4_sys_getdents64() similar to that in getdirentries(). - Mark ibcs2_getdents(), ibcs2_read(), linux_getdents(), linux_getdents64(), linux_readdir(), ogetdirentries(), svr4_sys_getdents(), and svr4_sys_getdents64() MPSAFE.
