Currently, we crash (issue BUG_ON) if backing swap disk size is zero. This can happen is user specified an extended partition or simply a bad disk as backing swap. A crash is really an unpleasant surprise to user for such trivial problems. Now, we check for this condition and simply fail device initialization if this is the case. Additional cleanups: * use static for all functions * remove extra newline between functions * memset backing_swap_name to NULL on device reset Signed-off-by:

ramzswap_free_page() already handles the case for zero filled pages. So, remove redundant logic for the same in ramzswap_write(). Signed-off-by:

Currently, we return 0 if create_device() fails and 1 otherwise. Now, proper error code is returned from create_device() and the same is propagated as module error code from ramzswap_init(). Also added some cleanups for ramzswap_init(), improving function structure. Signed-off-by:

ramzswap block size needs to be set equal to PAGE_SIZE to avoid receiving any unaligned block I/O requests (happens due to readahead logic during swapon). These unaligned accesses produce unnecessary I/O errors, scaring users. Signed-off-by:

64-bit stats corruption was observed when ramzswap was used on SMP systems. To prevent this, use separate spinlock to protect these stats. Also, replace stat_*() with rzs_stat*() to avoid possible conflict with core kernel code. Eventually, these will be converted to per-cpu counters if this driver finds use on large scale systems and this locking is found to affect scalability. Signed-off-by:
