/dev/zero is a special file in a Unix-like system that provides an infinite null character when the file is read. One of its main uses is to provide a character stream to initialize the data store, which is to overwrite the target data with a null character. Another common use is to produce a blank file of a specific size.You can read a null character of any size from/dev/zero. Unlike/

The struct Iommu_group *group can be obtained from the device structure; For example: struct Iommu_group *iommu_group_get (struct device *dev) { struct Iommu_group *group = dev->iommu_group; if (group) Kobject_get (Group->devices_kobj); return group; } Group = Iommu_group_get (dev); And Iommu_group has included Iommu_domain For example: domain = group->domain

In Linux, ">/dev/null 2> 1" is often encountered in both crontab and Common commands ". For example, in a crontab job, if you do not want to send an email, you can use either of the following methods: First, set mailto = "" to null.

TMPFS can use your memory or swap partition to store files (that is, its storage space isVirtual Memoryin, the VMbyReal Memoryand theSwapcomposition). Thus, TMPFS primarily stores staged files. It has the following 2 advantages: 1. The size of the dynamic file

Transferred from: http://loofeer.blog.51cto.com/707932/791065The default system will load/DEV/SHM, which is called TMPFS, some say with RAMDisk (virtual disk), but not the same. Like a virtual disk, TMPFS can use your RAM, but it can also be stored using your swap partition. And the traditional virtual disk is a block device, and requires a command such as MKFS to really use it, TMPFS is a file system, not a block device; you just install it and it's

Tmpfs File System in Linux (/dev/shm) Introduction /Dev/shm/is a device that uses the tmpfs file system. It is actually a special file system. In redhat, the default size is half of the physical memory, and mkfs format is not required for use. Tmpfs is a memory-based Virtual File System on Linux/Unix systems. Tmpfs can use your memory or swap partition to store files (that is, its storage space is in virtua
