Description of problem: find_first_bit and find_next_bit need the _sb_findmap table, but that's not exported (in 2.4.21-15.EL and prior at least), so they can't be used from modules. Fix is to EXPORT_SYMBOL_NOVERS(_sb_findmap); in s390_ksyms.c, for both the s390 and s390x arches. This is already in 2.6 upstream, and accordingly it looks like RHEL4 doesn't have this problem. Version-Release number of selected component (if applicable): 2.4.21-15.EL How reproducible: Try to compile and load a module that uses find_first_bit or find_next_bit (e.g., ocfs2)
