Maybe my last tests are just too long ago. But this means also that I still can have data loss if the system crashes while writing to the disk. It would be really nice if the filesystem would provide such a mechanism in the future. > How does the file system know that the file has "successfully been > written"? Does the filesystem really not know if the file is complete? If this could be achieved a transaction safety should be not the problem here. > If you think it can be done, plesae submit patches. :-) Sure I would if: - My experience with C would be a little higher. - Or at least if I would have the time to make a deeper look into the sourcecode and the coding rules for the kernel. I have posted the last few years many hundred bugs/feature requests in ~100 different projects and am still doing this many times a week. But don't worry, they don't have so many bogus reports as I'm reporting here :) The kernel is really a difficult place if you are not directly involved with it but want to improve something. But some of my tickets here had already success. Also I'm programming on own projects and this all together consumes much time. -- You are receiving this mail because: You are watching the assignee of the bug.
