Introduction The series is one of the proposals on how to transition VFS timestamps to use 64 bit time. This is the inode_timespec idea proposed in the original RFC series. The type name has been changed to vfs_time based on Dave Chinner’s suggestion.
Solution This series defines a new type name for vfs timestamps: vfs_time. All the individual file systems will use struct vfs_time to access vfs timestamps. Current time APIs also return vfs times and are considered to be part of vfs as they are exclusively used for inode timestamps. These are the steps involved: 1.Define vfs_time as an alias to timespec 2.Change individual filesystems to use only vfs_time data type for timestamps. Make sure each filesystem will be safe when converted to use timespec64 3.Change vfs_time to be an alias for timespec64. 4.Change all filesystems to use timespec64 directly. Note that the series only includes patches for steps 1 and 2. Concerns 1.Before the vfs layer is done, it might be confusing to developers as individual filesystems now will have two options for access: timespec and vfs_time type.
