Well, there is no document atm and I tried to explain how it is supposed to work in the patches that restart file-locks (patches 4. 9, 16). | | I'm trying to figure out how the file lock checkpoint will work with | cluster filesystems, or if there needs to be a mechanism to turn this | feature off for those filesystems. What prevents the lock state changing | in an incompatible way between the checkpoint and the restore? But I see that your question is about the bigger picture. Given that this question was asked on the previous version of the patchset, I will add a FAQ/description in patch 0 next time. For now, please see: http://marc.info/?l=linux-fsdevel&m=127657580718791&w=2
Would probably be a good idea to put something on the wiki and/or inside Documentation/checkpoint/...
