Hi, While analysing an xfstest failure (generic/258) I had to look at the definition of struct ceph_timespec. And I was surprised to verify that both its fields (tv_sec and tv_nsec) are 32-bits (__le32). And I believe that this explains the test failure, as ceph_encode_timespec() would fail to convert the negative pre-epoch value (-315615540 => 3979351756). The failure can be easily reproduced by simply creating a test file in a cephfs mount with: $ touch -t 196001010101 /mnt/testfile $ ls -l /mnt/testfile -rw-r--r-- 1 root 0 0 Jan 1 1960 testfile After remounting the filesystem: $ ls -l /mnt/testfile -rw-r--r-- 1 root 0 0 Feb 6 2096 testfile Am I missing something? If I'm not (and I probably am!), this isn't just a client-side issue and fixing it will require touching several other parts of the code.
