Vadim,
The patch is not "Make BUF_READ_AHEAD_AREA a constant".
But "Don't start up when small BP for which 64 page BUF_READ_AHEAD_AREA is too large".
So. I don't understand "working with default BP" meaning. The patch is for "don't start up when small BP such as default".
And for small BP, BUF_READ_AHEAD_AREA should not be 64. it is too large. (e.g. BP = 8MB, read ahed 1MB? why do you think it is needed?)
