From: Jeff Mahoney <jeffm@xxxxxxxx> Hi all - I recently had a bug report where xfs_repair in the dracut initramfs environment was crashing. It turned out to be due to systemd setting up cgroup pids limits and pthread_create was failing. The "real" fix is to remove that limit, but it created a easily reproducable scenario with which to test thread creation failure recovery. A combination of a small pids limit and MALLOC_PERTURB_ shook out a few bugs. There's more work to be done here since it should probably fall back to single threads whenever we can't create a thread, but I only tackled the cases that were already being handled gracefully instead of erroring out. -Jeff --- Jeff Mahoney (3): xfs_repair: clear pthread_t when pthread_create fails xfs_repair: add prefetch trace calls to debug thread creation failures xfs_repair: fix thread creation failure recovery repair/prefetch.c | 49 ++++++++++++++++++++++++++++++++++++++++++------- 1 file changed, 42 insertions(+), 7 deletions(-) -- 2.7.1 -- To unsubscribe from this list: send the line "unsubscribe linux-xfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
