Kirk McKusick 1a75045196 After the unlink() of one name of a file with multiple links, a ... stat() of one of the remaining names of the file does not show an updated ctime (inode modification time) until several seconds after the unlink() completes. The problem only occurs when the filesystem is running with soft updates enabled. When running with soft updates, the ctime is not updated until the soft updates background process has settled all the needed I/O operations. This commit causes the ctime to be updated immediately during the unlink(). A side effect of this change is that the ctime is updated again when soft updates has finished its processing because that is the time that is correct from the perspective of programs that look at the disk (like dump). This change does not cause any extra I/O to be done, it just ensures that stat() updates the ctime before handing it back.
