By this, we no longer need to keep buffer for the 1st bitmap during cyclic process. Note that this patch only deal with a conversion from ELF to kdump-compressed format only, not from ELF to ELF. --- HATAYAMA Daisuke (2): Use memset() to improve the 1st bitmap initialization performance Write out a whole part of the 1st bitmap before entering cyclic process makedumpfile.c | 252 ++++++++++++++++++++++++++++++++++++++++++++++++++------ 1 file changed, 227 insertions(+), 25 deletions(-) -- Thanks.
