Unfortunately it is not easy for me to add pagecache support to ncpfs, as couple of ncpfs users uses ncpfs in shared environment with database record locking, and if I'll now read full 4KB instead of 128B record, it can clash with records locked by other clients.
I can for sure add `leases' like Novell Client for Windows does for possibility of file caching, but I'm not sure whether size of code needed for supporting this (and for supporting server driven cache flushes) is worth of effort. Best regards, Petr Vandrovec vandrove@vc.cvut.cz
P.S.: And as NCP protocol is totally synchronous (even if it uses TCP, I explicitly asked in Utah), only local file caching can increase ncpfs performance, as there is no such thing like asynchronous file read/write... - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
