This is in preparation for improved page cache reclaim, which requires greater integration between the page cache and page allocator. PiperOrigin-RevId: 238444706 Change-Id: Id24141b3678d96c7d7dc24baddd9be555bffafe4

2018-12-17Implement mlock(), kind of.Jamie Liu
Currently mlock() and friends do nothing whatsoever. However, mlocking is directly application-visible in a number of ways; for example, madvise(MADV_DONTNEED) and msync(MS_INVALIDATE) both fail on mlocked regions. We handle this inconsistently: MADV_DONTNEED is too important to not work, but MS_INVALIDATE is rejected. Change MM to track mlocked regions in a manner consistent with Linux. It still will not actually pin pages into host physical memory, but: - mlock() will now cause sentry memory management to precommit mlocked pages. - MADV_DONTNEED and MS_INVALIDATE will interact with mlocked pages as described above.

2018-10-08Implement shared futexes.Jamie Liu
- Shared futex objects on shared mappings are represented by Mappable + offset, analogous to Linux's use of inode + offset. Add type futex.Key, and change the futex.Manager bucket API to use futex.Keys instead of addresses. - Extend the futex.Checker interface to be able to return Keys for memory mappings. It returns Keys rather than just mappings because whether the address or the target of the mapping is used in the Key depends on whether the mapping is MAP_SHARED or MAP_PRIVATE; this matters because using mapping target for a futex on a MAP_PRIVATE mapping causes it to stop working across COW-breaking. - futex.Manager.WaitComplete depends on atomic updates to futex.Waiter.addr to determine when it has locked the right bucket, which is much less straightforward for struct futex.Waiter.key. Switch to an atomically-accessed futex.Waiter.bucket pointer. - futex.Manager.Wake now needs to take a futex.Checker to resolve addresses for shared futexes. CLONE_CHILD_CLEARTID requires the exit path to perform a shared futex wakeup (Linux: kernel/fork.c:mm_release() => sys_futex(tsk->clear_child_tid, FUTEX_WAKE, ...)). This is a problem because futexChecker is in the syscalls/linux package. Move it to kernel. PiperOrigin-RevId: 216207039 Change-Id: I708d68e2d1f47e526d9afd95e7fed410c84afccf
2018-09-04Distinguish Element and Linker for ilist.Adin Scannell
Furthermore, allow for the specification of an ElementMapper. This allows a single "Element" type to exist on multiple inline lists, and work without having to embed the entry type. This is a requisite change for supporting a per-Inode list of Dirents. PiperOrigin-RevId: 211467497 Change-Id: If2768999b43e03fdaecf8ed15f435fe37518d163
