Subject: [PATCH] ramfs: change Elocked error string to Go expectation
Message-ID: <20200611200250.GA114633@delta.localdomain>

Go expects the error to be one of the three errors returned in
Bell Labs Plan 9. As listed in
https://github.com/golang/go/blob/f7ba82d68f90e20aa9e6aa973cb6f12321abec71/src/cmd/go/internal/lockedfile/lockedfile_plan9.go#L16:

	// Opening an exclusive-use file returns an error.
	// The expected error strings are:
	//
	//  - "open/create -- file is locked" (cwfs, kfs)
	//  - "exclusive lock" (fossil)
	//  - "exclusive use file already open" (ramfs)
	var lockedErrStrings = [...]string{
		"file is locked",
		"exclusive lock",
		"exclusive use file already open",
	}
