2013-03-20xfstests: add background noise to test 276 (btrfs backref resolving)Jan Schmidt
The backref resolver test for btrfs was run on a static file system so far. Resolving backrefs on a busy file system is what happens in reality and that is what should be checked by this test. I added a parameter such that the script can easily be changed to the former behavior for development purposes. Furthermore, this increases two constants which make the test simply cycle a few seconds longer, increasing the chance to hit on something suspicious in case we broke something.

2013-03-19xfstests: exclude largefs fill files from dump testsDave Chinner
The xfsdump/restore tests will see the space filling files and may try to back them up and restore them, consuming huge amounts of time to do (especially when diffing the results). Exclude the space filling files by setting the no dump attributes on them and ensure that xfsdump runs with the -e flag to exclude such files. This also needs a dump filter addition to remove the output that files were skipped, and to decrement the count of files processed by xfsrestore because the inventory still includes excluded files.

2013-03-19xfstests: use preallocation for ag-wiperDave Chinner
To enable sane testing of large scale filesystems, the --large-fs test option uses xfs_db magic to mark AGs full without doing any IO. This leaves only a small amount of free space left in the filesystem to stress the high AGs of the filesystem rather than the low AGs. This method requires us to have special filesystem check options to avoid free space checking in xfs_check, and we cannot current run xfs_repair on such a filesystem at all. As it is, free space checking on xfs_check does not scale, so we still need to avoid this checking regardless of how we fill the filesystem. We can achieve exactly the same fill behavior by preallocating a single large file in the filesystem immediately after creating it. This is a filesystem independent manner of filling the filesystem, and allows us to do large filesystem testing on more than just XFS. Further, this preallocation method effectively adds a new "very large file" test. It also enables us to run an unmodified xfs_repair or filesystem specific fsck program to check the filesystem for sanity, so we can now do full sanity checking of such large filesystems.

However this is not always possible and convenient, eg. in repeated automated tests where the required information is lost after the test round finished.

In other words: 1) Kernel should not panic 2) Memory should not leak 3) Data integrity operations (sync,fsync,fdatasync, directio) should fail for affected filesystem 4) It should be possible to umount broken filesystem Later when disk becomes available again we expect(only for journaled filesystems): 5) It will be possible to mount filesystem w/o explicit fsck (in order to catch issues like https://patchwork.kernel.org/patch/1983981/) 6) Filesystem should be operational 7) After mount/umount has being done all errors should be fixed so fsck should not spot any issues. This test use fault injection (CONFIG_FAULT_INJECTION=y, CONFIG_FAIL_MAKE_REQUEST=y and CONFIG_FAULT_INJECTION_DEBUG_FS=y config options) to force all new IO requests to fail for a given device. Xfs already has XFS_IOC_GOINGDOWN ioctl which provides similar behavior, but it is fs specific and it does it in an easy way because it performs freeze_bdev() before actual shutdown.
