I am not sure what level of testing Amit has done about the fallocate() and preallocation code on various archs. I couldn't find a available s390 and ia64 machines with free partition yet. In any case, it would be useful to add a new set of testsuites for the new fallocate() syscall and fsstress in LTP testsuites to automatically the preallocation code in ext4/XFS. thanks, Mingming > Thanks, > > - Ted > > P.S.
