[make-initrd] [PATCH 0/3] New locking functions based on flock utility

[Alexey Gladkov]

Привет!

Чтобы избавиться от лишнего поллинга в реализации блокировок я сделал другой
API основанный на flock из busybox. Добавилась возможность делать shared locks.

Я не стал использовать bash-builtin-lockf, который использует hasher, потому что
не хочу завязываться на версию bash и тянуть зависимость на bash-devel.

Как следствие блокировка может утечь в запускаемый под блокировкой код и теперь
за этим нужно следить.

Далее нужно будет провести рефакторинг и посмотреть нельзя ли сократить код под
блокировкой.
