[LTP] [PATCH 2/3] syscalls/preadv203: don't treat short write() as failure

[Jan Stancek]

Test is sporadically running into TBROK in setup() due to short write:
  tst_test.c:1064: TINFO: Formatting /dev/loop0 with xfs opts='' extra opts=''
  preadv203.c:257: TBROK: write(501,0x3fff4ef7d15,4123) failed: SUCCESS (0)

Switch to SAFE_WRITE_FULLY().
