procmeminfo: fix race in IsSmapsRollupSupported 2021-02-26T02:21:19+00:00 Tim Murray timmurray@google.com 2021-02-24T22:54:34+00:00 422e9a2bffaed5ad0d8d8d286b57d2e5e8cc3727 smaps_rollup is falsely reported as unsupported in some cases. One possible cause is that the process whose PSS is checked is killed so /proc/<pid>/smaps_rollup is not present, which then causes libmeminfo to assume that smaps_rollup is unsupported. Instead, when checking for smaps_rollup support, check for the existence of smaps_rollup belonging to the current process since that process is by definition alive.

smaps_rollup is falsely reported as unsupported in some cases. One
possible cause is that the process whose PSS is checked is killed so
/proc/<pid>/smaps_rollup is not present, which then causes libmeminfo
to assume that smaps_rollup is unsupported.

Instead, when checking for smaps_rollup support, check for the
existence of smaps_rollup belonging to the current process since that
