The patch titled Mark res_counter_charge(_locked) with __must_check has been removed from the -mm tree. Its filename was mark-res_counter_charge_locked-with-__must_check.patch This patch was dropped because it was merged into mainline or a subsystem tree The current -mm tree may be found at http://userweb.kernel.org/~akpm/mmotm/ ------------------------------------------------------ Subject: Mark res_counter_charge(_locked) with __must_check From: Pavel Emelyanov <xemul@xxxxxxxxxx> Ignoring their return values may result in counter underflow in the future - when the value charged will be uncharged (or in "leaks" - when the value is not uncharged). This also prevents from using charging routines to decrement the counter value (i.e. uncharge it) ;) (Current code works OK with res_counter, however :) ) Signed-off-by: Pavel Emelyanov <xemul@xxxxxxxxxx> Cc: Balbir Singh <balbir@xxxxxxxxxxxxxxxxxx> Cc: Paul Menage <menage@xxxxxxxxxx> Cc: KAMEZAWA Hiroyuki <kamezawa.hiroyu@xxxxxxxxxxxxxx> Signed-off-by: Andrew Morton <akpm@xxxxxxxxxxxxxxxxxxxx> --- include/linux/res_counter.h | 6 ++++-- 1 file changed, 4 insertions(+), 2 deletions(-) diff -puN include/linux/res_counter.h~mark-res_counter_charge_locked-with-__must_check include/linux/res_counter.h --- a/include/linux/res_counter.h~mark-res_counter_charge_locked-with-__must_check +++ a/include/linux/res_counter.h @@ -95,8 +95,10 @@ void res_counter_init(struct res_counter * counter->limit _locked call expects the counter->lock to be taken */ -int res_counter_charge_locked(struct res_counter *counter, unsigned long val); -int res_counter_charge(struct res_counter *counter, unsigned long val); +int __must_check res_counter_charge_locked(struct res_counter *counter, + unsigned long val); +int __must_check res_counter_charge(struct res_counter *counter, + unsigned long val); /* * uncharge - tell that some portion of the resource is released _ Patches currently in -mm which might be from xemul@xxxxxxxxxx are origin.patch memrlimit-add-memrlimit-controller-documentation.patch memrlimit-setup-the-memrlimit-controller.patch memrlimit-cgroup-mm-owner-callback-changes-to-add-task-info.patch memrlimit-add-memrlimit-controller-accounting-and-control.patch memrlimit-improve-error-handling.patch memrlimit-improve-error-handling-update.patch memrlimit-handle-attach_task-failure-add-can_attach-callback.patch reiser4.patch -- To unsubscribe from this list: send the line "unsubscribe mm-commits" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
