I ran into a linker warning in XFS that originates from a mismatch between libelf, binutils and objtool when certain files in the kernel are built with "gcc -g": x86_64-linux-ld: fs/xfs/xfs_trace.o: unable to initialize decompress status for section .debug_info After some discussion, nobody could identify why xfs sets this flag here. CONFIG_XFS_DEBUG used to enable lots of unrelated settings, but now its main purpose is to enable extra consistency checks and assertions that are unrelated to the debug info. Remove the Makefile logic to set the flag here. If anyone relies on the debug info, this can simply be enabled again with the global CONFIG_DEBUG_INFO option. Dave Chinner writes: I'm pretty sure it was needed for the original kgdb integration back in the early 2000s. That was when SGI used to patch their XFS dev tree with kgdb and debug symbols were needed by the custom kgdb modules that were ported across from the Irix kernel debugger. ISTR that the early kcrash kernel dump analysis tools (again, originated from the Irix "icrash" kernel dump tools) had custom XFS debug scripts that needed also the debug info to work correctly... Which is a long way of saying "we don't need it anymore" instead of "nobody knows why it was set"... :) Suggested-by: NChristoph Hellwig <hch@infradead.org> Link: https://lore.kernel.org/lkml/20200409074130.GD21033@infradead.org/Signed-off-by: NArnd Bergmann <arnd@arndb.de> Reviewed-by: NBrian Foster <bfoster@redhat.com> Reviewed-by: NAllison Collins <allison.henderson@oracle.com> Reviewed-by: NDave Chinner <dchinner@redhat.com> Reviewed-by: NDarrick J.

The initial value of variable udqp is NULL, and we only set the flag XFS_QMOPT_PQUOTA in xfs_qm_vop_dqalloc() function, so only the pdqp value is initialized and the udqp value is still NULL.
