Question: how to invalidate read cache

[Guven Demir]

hi all,

i hope this is the right place to ask question... anyway, it goes like this:

how can i invalidate the read cache for a file system?

the reason i'm asking this question is:

i'm mounting this ntfs partition to my linux box r/o, which i also
used by "another os" running under vmware r/w.

so when this partition gets updated under vmware, linux does not get
the changes until i umount / mount the partition again.

the problem is, i cant do this when the partiton is busy so i'm stuck
with invalid directory entries etc...

so, is there a way to disable or invalidate the read cache for this partition?

thanks in advance.
