2.6.30-stable review patch. If anyone has any objections, please let us know. ------------------ From: Csaba Henk commit b4c458b3a23d76936e76678f2074b1528f129f7a upstream. On 64 bit systems -- where sizeof(ssize_t) > sizeof(int) -- the following test exposes a bug due to a non-careful return of an int or unsigned value: implement a FUSE filesystem which sends an unsolicited notification to the kernel with invalid opcode. The respective write to /dev/fuse will return (1 << 32) - EINVAL with errno == 0 instead of -1 with errno == EINVAL.
