[PATCH V4 0/5] makedumpfile: --split: assign fair I/O workloads in appropriate time

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



v3->v4:
	1.address Atsushi Kumagai's comments about using divideup

v2->v3:
	1.remove the filtering for incomplete block (previous second pass) and adjust
	  relevant codes
	2.address HATAYAMA's comments about coding style

v1->v2:
	1.use splitblock instead of block
	2.add restriction (align to the page size) to splitblock size
	3.adjust the position of prepare_splitblock_table and check the return code
	4.use --splitblock-size to specify splitblock size and modify the print_info.c

the v2 test result is:
