SVN rev 218949 on 2011-02-22 14:47:10Z by alc
Eliminate two dubious attempts at optimizing the implementation of a
file's last accessed, modified, and changed times:
TMPFS_NODE_ACCESSED and TMPFS_NODE_CHANGED should be set unconditionally
in tmpfs_remove() without regard to the number of hard links to the file.
Otherwise, after the last directory entry for a file has been removed, a
process that still has the file open could read stale values for the last
accessed and changed times with fstat(2).
Similarly, tmpfs_close() should update the time-related fields even if all
directory entries for a file have been removed. In this case, the effect
is that the time-related fields will have values that are later than
expected. They will correspond to the time at which fstat(2) is called.
