Re: reiser4 mount options

[butdiene <butdiene@yahoo.com>]

I guess the solution for me is atom_min_size=0x100 or even smaller.

for a laptop, I don't want anything to hang, even at cost of general fs
performance.

/dev/root / reiser4
rw,atom_max_size=0x100,atom_max_age=0x927c0,atom_min_size=0x100,atom_max_flushers=0x1,cbk_cache_slots=0x10
0 0
