To clarify the supported filesystems by fstests, add a fs list to README file. Signed-off-by: Zorro Lang <zlang@xxxxxxxxxx> --- Hi, David Sterba suggests to have a supported fs list in fstests: https://lore.kernel.org/fstests/20250227073535.7gt7mj5gunp67axr@xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx/T/#m742e4f1f6668d39c1a48450e7176a366e0a2f6f9 I think that's a good suggestion, so I send this patch now. But tell the truth, it's hard to find all filesystems which are supported by fstests. Especially some filesystems might use fstests, but never be metioned in fstests code. So please review this patch or send another patch to tell fstests@ list, if you know any other filesystem is suppported. And if anyone has review point about the support "level" and "comment" part, please feel free to tell me :) Thanks, Zorro README | 82 ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 82 insertions(+) diff --git a/README b/README index 024d39531..055935917 100644 --- a/README +++ b/README @@ -1,3 +1,85 @@ +_______________________ +SUPPORTED FS LIST +_______________________ + +History +------- + +Firstly, xfstests is the old name of this project, due to it was originally +developed for testing the XFS file system on the SGI's Irix operating system. +With xfs was ported to Linux, so was xfstests, now it only supports Linux. + +As xfstests has some test cases are good to run on some other filesystems, +we call them "generic" (and "shared", but it has been removed) cases, you +can find them in tests/generic/ directory. Then more and more filesystems +started to use xfstests, and contribute patches. Today xfstests is used +as a file system regression test suite for lots of Linux's major file systems. +So it's not "xfs"tests only, we tend to call it "fstests" now. + +Supported fs +------------ + +Firstly, there's not hard restriction about which filesystem can use fstests. +Any filesystem can give fstests a try. + +Although fstests supports many filesystems, they have different support level +by fstests. So mark it with 4 levels as below: + +L1: Fstests can be run on the specified fs basically. +L2: Rare support from the specified fs list to fix some generic test failures. +L3: Normal support from the specified fs list, has some own cases. +L4: Active support from the fs list, has lots of own cases. + ++------------+-------+---------------------------------------------------------+ +| Filesystem | Level | Comment | ++------------+-------+---------------------------------------------------------+ +| AFS | L1 | N/A | ++------------+-------+---------------------------------------------------------+ +| Bcachefs | L1+ | N/A | ++------------+-------+---------------------------------------------------------+ +| Btrfs | L4 | N/A | ++------------+-------+---------------------------------------------------------+ +| Ceph | L2 | N/A | ++------------+-------+---------------------------------------------------------+ +| CIFS | L2- | https://wiki.samba.org/index.php/Xfstesting-cifs | ++------------+-------+---------------------------------------------------------+ +| Ext2/3/4 | L3+ | N/A | ++------------+-------+---------------------------------------------------------+ +| Exfat | L1+ | N/A | ++------------+-------+---------------------------------------------------------+ +| f2fs | L3- | N/A | ++------------+-------+---------------------------------------------------------+ +| FUSE | L1 | N/A | ++------------+-------+---------------------------------------------------------+ +| GFS2 | L1 | N/A | ++------------+-------+---------------------------------------------------------+ +| Glusterfs | L1 | N/A | ++------------+-------+---------------------------------------------------------+ +| JFS | L1 | N/A | ++------------+-------+---------------------------------------------------------+ +| NFS | L2+ | https://linux-nfs.org/wiki/index.php/Xfstests | ++------------+-------+---------------------------------------------------------+ +| ocfs2 | L2- | N/A | ++------------+-------+---------------------------------------------------------+ +| overlay | L3 | N/A | ++------------+-------+---------------------------------------------------------+ +| pvfs2 | L1 | N/A | ++------------+-------+---------------------------------------------------------+ +| Reiser4 | L1 | Reiserfs has been removed, only left reiser4 | ++------------+-------+---------------------------------------------------------+ +| tmpfs | L3- | N/A | ++------------+-------+---------------------------------------------------------+ +| ubifs | L1 | N/A | ++------------+-------+---------------------------------------------------------+ +| udf | L1+ | N/A | ++------------+-------+---------------------------------------------------------+ +| Virtiofs | L1 | N/A | ++------------+-------+---------------------------------------------------------+ +| XFS | L4+ | N/A | ++------------+-------+---------------------------------------------------------+ +| 9p | L1 | N/A | ++------------+-------+---------------------------------------------------------+ + _______________________ BUILDING THE FSQA SUITE _______________________ -- 2.47.1
