(#5222, #5237, #5226,\n #5229, #5239, #5249, #5269, #5287, #5295, #5304)\n * When masking directories with `maskPaths`, runc will now re-\n use a single `tmpfs` instance (which is not writeable) to\n reduce the number `tmpfs` superblocks that need to be reaped\n when containers die (in particular, Kubernetes applies masks\n to per-CPU sysfs directories which get expensive quickly).\n  \n- update to 1.3.5\n \n * Recursive atime-related mount flags (rrelatime et al.) are now applied\n properly. (#5115, #5098)\n * PR #4757 caused a regression that resulted in spurious\n cannot start a container that has stopped errors when\n running runc create and has thus been reverted. (#5158,\n #5153, #5151, #4645, #4757)\n * Updated builds to Go 1.25, libseccomp v2.6.0. (#5111, #5053)\n * Minor signing keyring updates.
