[Ocfs2-tools-devel] [PATCH] libocfs2: ocfs2_image_alloc_bitmap bug on handling ocfs2_malloc_blocks error code

[Norton.Zhu]

If malloc allocsize bitmap failed, it should try to malloc half of the allocsize.
ocfs2_image_alloc_bitmap had convert ENOMEM to OCFS2_ET_NO_MEMORY, so we have to
compare ret with OCFS2_ET_NO_MEMORY not -ENOMEM.
