  Modified files:
    sys/fs/tmpfs         tmpfs.h tmpfs_subr.c tmpfs_vnops.c 
  Log:
  MFp4:
   - LK_RETRY prohibits vget() and vn_lock() to return error.
     Remove associated code. [1]
   - Properly use vhold() and vdrop() instead of their unlocked
     versions, we are guaranteed to have the vnode's interlock
     unheld. [1]
   - Fix a pseudo-infinite loop caused by 64/32-bit arithmetic
     with the same way used in modern NetBSD versions. [2]
   - Reorganize tmpfs_readdir to reduce duplicated code.
