    btrfs: separate superblock items out of fs_info · 6c41761f
    David Sterba 提交于
    fs_info has now ~9kb, more than fits into one page. This will cause
    mount failure when memory is too fragmented. Top space consumers are
    super block structures super_copy and super_for_commit, ~2.8kb each.
    Allocate them dynamically. fs_info will be ~3.5kb. (measured on x86_64)
    
    Add a wrapper for freeing fs_info and all of it's dynamically allocated
    members.
