    bcachefs: Improved errcodes · 615f867c
    Kent Overstreet authored
    Instead of overloading standard error codes (EINTR/EAGAIN), and defining
    short lists of error codes in multiple places that potentially end up
    overlapping & conflicting, we're now going to have one master list of
    error codes.
    
    Error codes are defined with an x-macro: thus we also have
    bch2_err_str() now.
    
    Also, error codes have a class field. Now, instead of checking for
    errors with ==, code should use bch2_err_matches(), which returns true
    if the error is equal to or a sub-error of the error class.
    
    This means we can define unique errors for every source location where
    an error is generated, which will help improve our error messages.
