Bug ID: 235775
Summary: [FUSE]: Reuse cached attributes, when available and
valid
Product: Base System
Version: CURRENT
Hardware: Any
URL: https://robo.moosefs.com/support/fuse_helloworld.tgz
OS: Any
Status: New
Severity: Affects Some People
Priority: ---
Component: kern

Depends on: 230258
Blocks: 235773, 235774
When cached attributes are valid, save a round-trip through FUSE and return the
cached values in VOP_GETATTR.
(Ditto: use cache_enter and keep lookup dentries cached.)
This is a performance optimization rather than a correctness issue.
