2020-01-27Update package locations.Adin Scannell
Because the abi will depend on the core types for marshalling (usermem, context, safemem, safecopy), these need to be flattened from the sentry directory. These packages contain no sentry-specific details. PiperOrigin-RevId: 291811289
2020-01-09New sync package.Ian Gudger
* Rename syncutil to sync. * Add aliases to sync types. * Replace existing usage of standard library sync package. This will make it easier to swap out synchronization primitives. For example, this will allow us to use primitives from github.com/sasha-s/go-deadlock to check for lock ordering violations. Updates #1472 PiperOrigin-RevId: 289033387

2019-04-30Implement async MemoryFile eviction, and use it in CachingInodeOperations.Jamie Liu
This feature allows MemoryFile to delay eviction of "optional" allocations, such as unused cached file pages. Note that this incidentally makes CachingInodeOperations writeback asynchronous, in the sense that it doesn't occur until eviction; this is necessary because between when a cached page becomes evictable and when it's evicted, file writes (via CachingInodeOperations.Write) may dirty the page. As currently implemented, this feature won't meaningfully impact steady-state memory usage or caching; the reclaimer goroutine will schedule eviction as soon as it runs out of other work to do. Future CLs increase caching by adding constraints on when eviction is scheduled. PiperOrigin-RevId: 246014822 Change-Id: Ia85feb25a2de92a48359eb84434b6ec6f9bea2cb

2019-03-14Decouple filemem from platform and move it to pgalloc.MemoryFile.Jamie Liu
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
