FILE_UPDATE_TIME(9)                       The Linux VFS                       FILE_UPDATE_TIME(9)



NAME
       file_update_time - update mtime and ctime time

SYNOPSIS
       int file_update_time(struct file * file);

ARGUMENTS
       file
           file accessed

DESCRIPTION
       Update the mtime and ctime members of an inode and mark the inode for writeback. Note that
       this function is meant exclusively for usage in the file write path of filesystems, and
       filesystems may choose to explicitly ignore update via this function with the S_NOCMTIME
       inode flag, e.g. for network filesystem where these timestamps are handled by the server.
       This can return an error for file systems who need to allocate space in order to update an
       inode.
