Red Hat Bugzilla – Bug 126218
s390 kernels do not export _sb_findmap
Last modified: 2007-11-30 17:07:02 EST
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):
Try to compile and load a module that uses find_first_bit or
find_next_bit (e.g., ocfs2)
