Thanks for the patch. The 'bh' change is fine. The problems with 'i'
should be solved differently I think. Those functions UDF_SB_FREE,
UDF_SB_ALLOC_PARTMAPS should be functions and not macros. Please convert
those to either inline functions if they are small or to regular
functions if they are larger. It won't be completely trivial because of
the hackery e.g. in UDF_SB_ALLOC_BITMAP. It gets an argument meaning on
which struct member something should be performed. But for example in
the UDF_SB_ALLOC_BITMAP case you can simply make the function return the
pointer to allocated and initialized space and the caller would assign
it to a proper element of the superblock. This would help the overall
code quality of UDF (which is sadly quite poor). Thanks.

Thanks for the patch. The 'bh' change is fine. The problems with 'i'
should be solved differently I think. Those functions UDF_SB_FREE,
UDF_SB_ALLOC_PARTMAPS should be functions and not macros. Please convert
those to either inline functions if they are small or to regular
functions if they are larger. It won't be completely trivial because of
the hackery e.g. in UDF_SB_ALLOC_BITMAP. It gets an argument meaning on
which struct member something should be performed. But for example in
the UDF_SB_ALLOC_BITMAP case you can simply make the function return the
pointer to allocated and initialized space and the caller would assign
it to a proper element of the superblock. This would help the overall
code quality of UDF (which is sadly quite poor). Thanks.

[PATCH 6/6] udf: fix sparse warnings (shadowing mismatch between declaration and definition)
fix warnings:
fs/udf/super.c:1320:24: warning: symbol 'bh' shadows an earlier one
fs/udf/super.c:1240:21: originally declared here
fs/udf/super.c:1583:4: warning: symbol 'i' shadows an earlier one
fs/udf/super.c:1418:6: originally declared here
fs/udf/super.c:1585:4: warning: symbol 'i' shadows an earlier one
fs/udf/super.c:1418:6: originally declared here
fs/udf/super.c:1658:4: warning: symbol 'i' shadows an earlier one
fs/udf/super.c:1648:6: originally declared here
fs/udf/super.c:1660:4: warning: symbol 'i' shadows an earlier one
fs/udf/super.c:1648:6: originally declared here
fs/udf/super.c:450:6: warning: symbol 'udf_write_super' was not declared.
Should it be static?
