It's obviously correct and the only reason it hasn't been upstreamed is because they're still debating whether listxattr should return empty results or -ENOTSUPP over NFS. Having the kernel not crash is more pressing than the result of that debate. Patch applied to stable (3.15) and master (3.16). Kernels earlier than 3.14 are unaffected. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
