# DESCRIPTION:
|
|
# Test posix_fadvise.
|
|
#
|
|
# STRATEGY:
|
|
# 1. Set primarycache to metadata in order to disable prefetch
|
|
# 2. Write some data to file
|
|
# 3. get data_size field from arcstat
|
|
# 4. call file_fadvise with POSIX_FADV_SEQUENTIAL
|
|
# 5. get data_size field from arcstat again
|
|
# 6. latter data_size should be bigger than former one
|
|
#
|
|
|
|
# NOTE: if HAVE_FILE_FADVISE is not defined former data_size
|
|
# should less or eaqul to latter one
