1 stress2 is a tool for finding problems in the kernel.
3 It is composed of a large number of regression tests, tests that
4 stress various components of the kernel and a few validation tests.
5 There are currently some 700 different tests.
7 The key idea behind stress2 is to randomize as much as possible in
8 a test, as a way of achieving better coverage. For example, varying
9 VM pressure, varying numbers of threads, varying delays, etc.
10 stress2 has found a large number of problems:

13 To run the full test suite type "make test" in the stress2 directory.
15 To run a subset of tests, go to the stress2/misc directory.
16 To run for example all tmpfs tests, type ./all.sh -o $(grep -l tmpfs *.sh)
17 To run fdatasync.sh for one hour, type ./all.sh -m 60 fdatasync.sh"
18 To run dup2.sh three times, type ./all.sh -l 3 dup2.sh
