[pso] [Tema3 Linux] ioctl

[Florin Antonescu]

Am observat ca la executia lfunctiei ioctl(fd, SSR_IOCTL_SYNC, 0) din userspace, imi da Kernel Panic.
Eu am implementat ioctl astfel: apelez sync_blockdev pentru i->b_dev si cele doua block_device-uri (hdb1 si hdb2) apoi apelez invalidate_bdev pentru cele trei block_device-uri de mai inainte. Cam asa am dedus din lista de discutii.
Ce e gresit in implementarea asta?
