Fix three bugs in fs/omfs/: 1. In omfs_fill_super() and omfs_get_bucket() (fs/omfs/inode.c, fs/omfs/dir.c), validate s_mirrors > 0 and s_sys_blocksize large enough that nbuckets > 0, preventing a hardware divide-by-zero (#DE) trap, and fix the error path so sbi->s_imap is not double-freed. 2. In omfs_count_free(), omfs_allocate_block(), and set_run() (fs/omfs/bitmap.c), bounds-check bitmap block indices against sbi->s_imap_size and clamp bit runs to the block size. Fixes: 555e377 ("omfs: add inode routines") Assisted-by: LLM Signed-off-by: Hui Peng <benquike@gmail.com>
