My driver consistently hang after 3 or 4 successful
scsi commands been issued. From the messages file,
I'm getting hundreds of:
magic (corrupt) (name=size-256)
kmem_alloc: Bad slab magic (corrupt) .....
And it looks like I'm running out of memory. Am not
sure why because it does not look like my driver is
allocating the memory.
The driver isn't all that big, about 300K and I was
just allocating 56 bytes buffer for the inquiry data.
I use scsi_init_malloc with GFP_ATOMIC for allocating
the data buffer. If I changed it to scsi_malloc, I'd
then get segmentation fault instead of hang.
Whats the difference between these two malloc? Which
is the right one to use? Also, any rules on using
GFP_ATOMIC and GFP_KERNEL?
thanks.
