回复 12# 独孤九贱
啊啊啊 抱歉,不是slab_debug 是 slub_debug,
一般来说slub_debug=FUPZ 会比较小影响系统运行,系统可以正常跑下去。
see kernel\Documentation\vm\slub.txt
Parameters may be given to slub_debug. If none is specified then full
debugging is enabled. Format:
slub_debug=<Debug-Options> Enable options for all slabs
slub_debug=<Debug-Options>,<slab name>
Enable options only for select slabs
Possible debug options are
F Sanity checks on (enables SLAB_DEBUG_FREE. Sorry
SLAB legacy issues)
Z Red zoning
P Poisoning (object and padding)
U User tracking (free and alloc)
T Trace (please only use on single slabs)
A Toggle failslab filter mark for the cache
O Switch debugging off for caches that would have
caused higher minimum slab orders
- Switch all debugging off (useful if the kernel is
configured with CONFIG_SLUB_DEBUG_ON)
