  "message": "execve: improve interactivity with large arguments\n\nThis adds a preemption point during the copying of the argument and\nenvironment strings for execve, in copy_strings().  There is already\na preemption point in the count() loop, so this doesn\u0027t add any new\npoints in the abstract sense.\n\nWhen the total argument+environment strings are very large, the time\nspent copying them can be much more than a normal user time slice.\nSo this change improves the interactivity of the rest of the system\nwhen one process is doing an execve with very large arguments.\n\nSigned-off-by: Roland McGrath \u003croland@redhat.com\u003e\nReviewed-by: KOSAKI Motohiro \u003ckosaki.motohiro@jp.fujitsu.com\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n",
