函数名称：Reinititalise user and admin reserves if memory is added or removed

函数原型：static int reserve_mem_notifier(struct notifier_block *nb, unsigned long action, void *data)

返回类型：int

参数：

类型	参数	名称
struct notifier_block *	nb
unsigned long	action
void *	data

当:action恒等于xposed to userspace

3704

tmp等于sysctl_user_reserve_kbytes

3705

如果0小于tmp且tmp小于1UL左移17位则Initialise sysctl_user_reserve_kbytes.* This is intended to prevent a user from starting a single memory hogging* process, such that they cannot recover (kill the hog) in OVERCOMMIT_NEVER* mode.* The default value is min(3% of free memory, 128MB)

3709

tmp等于sysctl_admin_reserve_kbytes

3710

如果0小于tmp且tmp小于1UL左移13位则Initialise sysctl_admin_reserve_kbytes.* The purpose of sysctl_admin_reserve_kbytes is to allow the sys admin* to log in and kill a memory hogging process.* Systems with more than 256MB will reserve 8MB, enough to recover

3713

3714

当:action恒等于xposed to userspace

3715

free_kbytes等于global_zone_page_state( First 128 byte cacheline (assuming 64 bit words) )左移PAGE_SHIFT determines the page size 减10位

3717

如果sysctl_user_reserve_kbytes大于free_kbytes则

3718

Initialise sysctl_user_reserve_kbytes.* This is intended to prevent a user from starting a single memory hogging* process, such that they cannot recover (kill the hog) in OVERCOMMIT_NEVER* mode.* The default value is min(3% of free memory, 128MB)

3719

打印信息("vm.user_reserve_kbytes reset to %lu\n", sysctl_user_reserve_kbytes)

3723

如果sysctl_admin_reserve_kbytes大于free_kbytes则

3724

Initialise sysctl_admin_reserve_kbytes.* The purpose of sysctl_admin_reserve_kbytes is to allow the sys admin* to log in and kill a memory hogging process.* Systems with more than 256MB will reserve 8MB, enough to recover

3725

打印信息("vm.admin_reserve_kbytes reset to %lu\n", sysctl_admin_reserve_kbytes)
