Hi All,

According to this document:
http://docs.openafs.org/UserGuide/ch01s02.html#HDRWQ10

the note says:
"The callback mechanism does not guarantee that you immediately see the
changes someone else makes to a file you are using. Your Cache Manager does
not notice the broken callback until your application program asks it for
more data from the file."

Does that mean if we read for example first 100 Bytes of the file,
repeatedly, if main file changes, callbacks don't inform the cache manager,
until we read for example byte 101?

Regards
