7.t

xen 3.2.2 源码

/* 7.t
- Write overlapping the file size rlimit boundary: should be a short
  write. (7.t)
- Write at the file size rlimit boundary: should give EFBIG.  (I think
  the spec requires that you do NOT deliver SIGXFSZ in this case, where
  you would do so for sync IO.) (7.t)
- Special case: a write of zero bytes at or beyond the file size rlimit
  boundary must return success. (7.t)
