[LTP] [RFC PATCH 1/1] Remove fs-bench

Petr Vorel
2022-11-23T11:56:08Z

fs-bench is horribly broken and there does not seem to be a lot of value
in keeping it.

Closes: https://github.com/linux-test-project/ltp/issues/994

-Programs for File system stress test.
-
-All of programs are distributed under GPL 2 license
-by Hironobu SUZUKI <hironobu@h2np.net>
-
-HOW TO TEST
-------------
-
-1: Type "make"
-
- # cd
- # tar zxvf fs-bench.tar.gz
- # cd fs-bench
- # make
-
-2: Change directory to terget file system and do-it!
- (I always use one-HDD/one-partition for fs stress test.)
-
- # mount -t jfs /dev/hdc1 /jfs
- # cd /jfs
- # ~/fs-bench/test.sh 2>&1 | tee ~/fs-bench/jfs-test
-
-
-NOTE
------
-
-The size of files that are created for stress test is not fixed. The
-file size are determined by probabilistic algorithm, box-muler
-algorithm.
-
-number
-of files

-#To run this script the following is necessary
-# 1.kernel should mtd support as module.
-# 2.kernel should hsve jffs2 support as module.
-# 3.kernel should have loopback device support .
-# 4.you should have fs-bench utility (http://h2np.net/tools/fs-bench-0.2.tar.gz)
-# 5.results will be copied to /tmp/log and /tmp/log1 files
-
-#DESCRIPTION: This testscript creates a jffs2 file system type and tests the filesystem test
-#and places the log in the log directory.The file system test actually creates a tree of large
-#directories and performs the delete and random delete operations as per the filesystem stress
-#algorithim and gives a report of real time ,user time,system time taken to perform the file
-#operations.
