Subject: [PATCH v2 0/2] mm: optimize shadow entries removal

Some of our production workloads which processes a large amount of data
spends considerable amount of CPUs on truncation and invalidation of
large sized files (100s of GiBs of size). Tracing the operations showed
that most of the time is in shadow entries removal. This patch series
optimizes the truncation and invalidation operations.
