Looking at the debug output of a fusefs file system, the fuse daemon gets t= he FUSE_FALLOCATE operation before it ever sees the FUSE_WRITE, which seems wr= ong. I think the VFS needs to flush mapped pages in vn_deallocate_impl. --=20 You are receiving this mail because: You are the assignee for the bug.=
