I know this is not an extremely serious question but it is still worth
clarifying at least for historical purposes. In at least two places (TLK
and Linux Kernel Internals book) I saw the explanation of current->pwd as
originating from pwd(1) command "print working directory". I, however,
insist that pwd in the task_struct has nothing to do with the user-space
pwd(1) but rather means "present working directory", as a synonym for
"current working directory" cwd used by other Unix systems in the struct
proc.
Only the person who actually put pwd in task_struct (probably Linus) could
say for sure which version is right, but then he is probably too busy to
notice this... ;)
