Pull request overview
This PR adjusts the COVE restore flow to run the ProcessController under jemalloc (with THP disabled via MALLOC_CONF) to reduce RSS usage during filesystem restore, and fixes a variable name in the CI upload step.
Changes:
- Add
jemalloc-related defaults (COVE_USE_JEMALLOC,COVE_JEMALLOC_PATH,COVE_MALLOC_CONF) for BACKUP=COVE. - Update the COVE ProcessController startup to optionally set
LD_PRELOAD/MALLOC_CONFwhenjemallocis enabled. - Fix an invalid/unused variable name in
Jenkinsfileupload logic.
