--- Comment #15 from Martin Steigerwald <mar...@lichtvoll.de> --- In one of those bug reports we already established that this is not just about BTRFS. This is about kernel device major:minor numbers not guaranteed to be stable in various circumstances. We discussed all of this before. I even asked kernel developers. See here: https://bugs.kde.org/show_bug.cgi?id=438434#c14 In there I wrote: Neil Brown clearly said that no userspace component can rely on device numbers since kernel 2.4. Luckily he recommended an alternative: "That is really hard to provide in general. Possibly the best approach is to use the statfs() systemcall to get the "f_fsid" field. This is 64bits. It is not supported uniformly well by all filesystems, but I think it is at least not worse than using the device number. For a lot of older filesystems it is just an encoding of the device number. For btrfs, xfs, ext4 it is much much better." https://lore.kernel.org/linux-block/1769070.0rzTUBzp5V@ananda/T/#m28b8c889c9289ad1ec76cbf040938ea883e3f375 -- You are receiving this mail because: You are watching all bug changes.
