[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 Signed-off-by: Akinobu Mita <mita@miraclelinux.com> Signed-off-by: Dave Kleikamp <shaggy@austin.ibm.com> (cherry picked from 2b46f77976f798f3fe800809a1d0ed38763c71c8 commit)
