27 * TEST IDENTIFIER : sync_file_range01
28 *
29 * EXECUTED BY : anyone
30 *
31 * TEST TITLE : Checks for Errors from sync_file_range()
32 *
33 * TEST CASE TOTAL : 5
34 *
35 * CPU ARCHITECTURES : All
36 *
37 * AUTHOR : B N Poornima
38 *
39 * DATE STARTED : 21/07/2008
40 *
41 * TEST CASES
42 * (Tests sync_file_range() for different test cases as reported in the man
43 * page)
44 *
45 * INPUT SPECIFICATIONS
46 * No input needs to be specified
47 * sync_file_data() in-puts are specified through test_data
48 *
49 * OUTPUT SPECIFICATIONS
50 * sync_file_data() error message matches with the expected error
51 * message.
52 *
53 * ENVIRONMENTAL NEEDS
54 * Kernel version 2.6.17 and above
55 * Kernel version 2.6.22 and above in case of PPC and PPC64
56 *
57 * SPECIAL PROCEDURAL REQUIREMENTS
58 * None
59 *
60 * DETAILED DESCRIPTION
61 * This is a test case for sync_file_range() system call.
62 * This test suite tests various error messages from the system call
63 * If the error message received matches with the expected
64 * test is considered passed else test fails
65 *
66 * Total 5 Test Cases :-
67 * Various error messages from the man page
68 *
69 * Setup:
70 * Setup files on which sync_file_range is to be called
71 *
72 * Test:
73 * Loop if the proper options are given.
74 * Execute system call
75 * Check return code.
76 * If error obtained matches with the expected error
77 * PASS the test, otherwise TEST FAILS
78 *
79 * Cleanup:
80 * Cleanup the temporary folder
