sync mount

[spied@xxxxxxxxx]

i want use root xfs partition in sync mode (i don't need high wite
speed on it, and it's corruption stop server)

how can i do it? i fast see sources - "-o sync" option is ignored, but
exist option "-o wsync".
what do wsync flag? can i use it to avoid possible filesystem damage?

i use linux kernel 2.4.20-xfs from sgi and xfsprogs 2.0.3-1 from
debian

ps: sorry, my english is very bad
