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

# IOzone filesystem benchmark suite-level shared library
|
|
# Installs iozone, provides result parsing helpers.
|
|
#
|
|
# IOzone measures filesystem I/O performance with various
|
|
# access patterns: sequential/random read/write, etc.
|
|
#
|
|
# Key parameters:
|
|
# -a Auto mode (tests record sizes 4k-16M, files 64k-512M)
|
|
# -c Include close() in timing
|
|
# -I Direct I/O (bypass page cache)
|
|
# -s SIZE File size (e.g., 128m, 1g)
|
|
# -r SIZE Record size (e.g., 4k, 16m)
|
|
# -f FILE Test file path
|
|
#
|
|
# Result: throughput in kBytes/sec for each operation type
|
|
#
|
|
# Usage: . "$(dirname "$0")/../lib.sh"
