[PATCH] JFS: return correct error when i-node allocation failed
I have seen confusing behavior on JFS when I injected many intentional
slab allocation errors. The cp command failed with no disk space error
with enough disk space.
This patch makes:
- change the return value in case slab allocation failures happen
from -ENOSPC to -ENOMEM
- ialloc() return error code so that the caller can know the reason
of failures
