  "message": "mlock: avoid dirtying pages and triggering writeback\n\nWhen faulting in pages for mlock(), we want to break COW for anonymous or\nfile pages within VM_WRITABLE, non-VM_SHARED vmas.  However, there is no\nneed to write-fault into VM_SHARED vmas since shared file pages can be\nmlocked first and dirtied later, when/if they actually get written to.\nSkipping the write fault is desirable, as we don\u0027t want to unnecessarily\ncause these pages to be dirtied and queued for writeback.\n\nSigned-off-by: Michel Lespinasse \u003cwalken@google.com\u003e\nCc: Hugh Dickins \u003chughd@google.com\u003e\nCc: Rik van Riel \u003criel@redhat.com\u003e\nCc: Kosaki Motohiro \u003ckosaki.motohiro@jp.fujitsu.com\u003e\nCc: Peter Zijlstra \u003cpeterz@infradead.org\u003e\nCc: Nick Piggin \u003cnpiggin@kernel.dk\u003e\nCc: Theodore Tso \u003ctytso@google.com\u003e\nCc: Michael Rubin \u003cmrubin@google.com\u003e\nCc: Suleiman Souhlal \u003csuleiman@google.com\u003e\nCc: Dave Chinner \u003cdavid@fromorbit.com\u003e\nCc: Christoph Hellwig \u003chch@infradead.org\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n",
