As a bonus the code becomes less nested, and the "wakeup_write" flag variable becomes unnecessary. The variable "flags" was already unused. This code behaves identically to the previous version except in two pathological cases that don't occur. If the argument "nbytes" is already less than "min", then we didn't previously enforce "min". If r->limit is false while "reserved" is nonzero, then we previously applied "reserved" in checking whether we had enough bits, even though we don't apply it to actually limit how many we take. The callers of account() never exercise either of these cases. Before the previous commit, it was possible for "nbytes" to be less than "min" if userspace chose a pathological configuration, but no longer. Cc: Jiri Kosina Cc: "H.
