函数名称：Allocator uses a trailing node argument --------+ (e.g. kmalloc_node())* Allocator uses the gfp_t argument -----------+ | (e.g. kmalloc())* Allocator uses a special leading argument + | | (e.g. devm_kmalloc())* | | |

函数原型：static int __attribute__((__section__(".init.text"))) __attribute__((__cold__))test_kvmalloc_node(void *arg)

返回类型：int

参数：

类型参数名称
void *arg
556  a等于5乘4096
556  b等于0的反除5乘4096加1
556  ptr等于kvmalloc_node - attempt to allocate physically contiguous memory, but upon* failure, fall back to non-contiguous (vmalloc) allocation
556  如果非ptr则
556  printk("\0014"KBUILD_MODNAME": kvmalloc_node failed regular allocation?!\n", )
556  返回:1
556  kvfree() - Free memory.*@addr: Pointer to allocated memory.* kvfree frees memory allocated by any of vmalloc(), kmalloc() or kvmalloc().* It is slightly more efficient to use kfree() or vfree() if you are certain* that you know which one to use.
556  ptr等于kvmalloc_node - attempt to allocate physically contiguous memory, but upon* failure, fall back to non-contiguous (vmalloc) allocation
556  如果非ptr则
556  printk("\0014"KBUILD_MODNAME": kvmalloc_node unexpectedly failed bad wrapping?!\n", )
556  返回:1
556  kvfree() - Free memory.*@addr: Pointer to allocated memory.* kvfree frees memory allocated by any of vmalloc(), kmalloc() or kvmalloc().* It is slightly more efficient to use kfree() or vfree() if you are certain* that you know which one to use.
556  ptr等于kvmalloc_node - attempt to allocate physically contiguous memory, but upon* failure, fall back to non-contiguous (vmalloc) allocation
556  如果ptr则
556  printk("\0014"KBUILD_MODNAME": kvmalloc_node missed saturation!\n", )
556  kvfree() - Free memory.*@addr: Pointer to allocated memory.* kvfree frees memory allocated by any of vmalloc(), kmalloc() or kvmalloc().* It is slightly more efficient to use kfree() or vfree() if you are certain* that you know which one to use.
556  返回:1
