This series attempts to address all those problems by building a set of wrappers and fixing some of the internal logic. Thank you Rasmus for the suggestions (and the "jobhog" example)! :) -Kees [1] https://lore.kernel.org/lkml/eb25959a-9ec4-3530-2031-d9d716b40b20@rasmusvillemoes.dk Kees Cook (3): docs, parallelism: Fix failure path and add comment docs, parallelism: Do not leak blocking mode to other readers docs, parallelism: Rearrange how jobserver reservations are made Documentation/Makefile | 5 +- Documentation/sphinx/parallel-wrapper.sh | 33 ++++++++++++ scripts/jobserver-count | 58 --------------------- scripts/jobserver-exec | 66 ++++++++++++++++++++++++ 4 files changed, 101 insertions(+), 61 deletions(-) create mode 100644 Documentation/sphinx/parallel-wrapper.sh delete mode 100755 scripts/jobserver-count create mode 100755 scripts/jobserver-exec -- 2.17.1
