fuse: implement statx
Allow querying btime. When btime is requested in mask, then FUSE_STATX
request is sent. Otherwise keep using FUSE_GETATTR.
The userspace interface for statx matches that of the statx(2) API.
However there are limitations on how this interface is used:
- returned basic stats and btime are used, stx_attributes, etc. are
ignored
- always query basic stats and btime, regardless of what was requested
- requested sync type is ignored, the default is passed to the server
- if server returns with some attributes missing from the result_mask,
then no attributes will be cached
- btime is not cached yet (next patch will fix that)
For new inodes initialize fi->inval_mask to "all invalid", instead of "all
valid" as previously. Also only clear basic stats from inval_mask when
caching attributes. This will result in the caching logic not thinking
that btime is cached.
