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.
