Hello! I see that you have introduced in commit 62750d0 two new IOCTLs for filesyetems: FS_IOC_GETFSLABEL and FS_IOC_SETFSLABEL. I would like to ask, are these two new ioctls mean to be generic way for userspace to get or set fs label independently of which filesystem is used? Or are they only for btrfs? Because I was not able to find any documentation for it, what is format of passed buffer... null-term string? fixed-length? and in which encoding? utf-8? latin1? utf-16? or filesystem dependent? -- Pali Rohár pali.rohar@xxxxxxxxx
