block: fix part_pack_uuid() build error
Commit "85865c1 ima: add policy support for file system uuid" introduced a CONFIG_BLOCK dependency. This patch defines a wrapper called blk_part_pack_uuid(), which returns -EINVAL, when CONFIG_BLOCK is not defined. security/integrity/ima/ima_policy.c:538:4: error: implicit declaration of function 'part_pack_uuid' [-Werror=implicit-function-declaration] Changelog v2: - Reference commit number in patch description Changelog v1: - rename ima_part_pack_uuid() to blk_part_pack_uuid() - resolve scripts/checkpatch.pl warnings Changelog v0: - fix UUID scripts/Lindent msgs Reported-by: Randy Dunlap <rdunlap@infradead.org> Reported-by: David Rientjes <rientjes@google.com> Signed-off-by: Mimi Zohar <zohar@linux.vnet.ibm.com> Acked-by: David Rientjes <rientjes@google.com> Acked-by: Randy Dunlap <rdunlap@infradead.org> Cc: Jens Axboe <axboe@kernel.dk> Signed-off-by: James Morris <james.l.morris@oracle.com>
