Subject: [PATCH v2 06/92] cifs: update the ctime on a partial page write
Date:   Wed,  5 Jul 2023 15:00:33 -0400

POSIX says:

    "Upon successful completion, where nbyte is greater than 0, write()
     shall mark for update the last data modification and last file status
     change timestamps of the file..."

Add the missing ctime update.
