All .sh files under tests/ lacked the Git executable permission bit (100644 instead of 100755), causing tmt run to fail with 'permission denied' errors on Linux servers. Fixes: woqidaideshi/openruyi-autotest#80

# fio (Flexible I/O Tester) suite-level shared library
|
|
# Measures OS storage I/O performance: throughput, IOPS, latency.
|
|
#
|
|
# Key parameters (from Testing-Guide):
|
|
# - rw: read/write/randread/randwrite/randrw
|
|
# - bs: block size (4k,16k,32k,64k,128k,256k,512k,1024k)
|
|
# - direct=1: O_DIRECT, bypass page cache
|
|
# - ioengine=libaio: Linux async I/O
|
|
# - numjobs: concurrent job count
|
|
# - iodepth: I/O queue depth per job
|
|
# - runtime: test duration
|
|
# - group_reporting: aggregate all jobs
|
|
#
|
|
# Results: BW (bandwidth), IOPS, latency (slat/clat/lat)
|
|
# - Geometric mean across block sizes = overall score
|
|
# - Run 3x, take average (per Testing-Guide)
|
|
#
|
|
# Usage: . "$(dirname "$0")/../lib.sh"
