I generally think 10-15 patches are reasonable. But it also depends on
the patch size and the nature of the changes.
For me, the deciding factors are:
1. What's the point of this series?
2. Can I complete review of this series within 30 minutes before my next

First of all, as a subsystem maintainer I rely heavily on other people
to review patches. Either individual driver maintainers or people with a
vested interest in SCSI (enterprise distro developers).
It's virtually impossible to entice people to review patches in the
first place. Forcing people to go switch from their email context to go
peruse the lkml archives in a web browser to decide whether a patch
series is worth reviewing in the first place is a non-starter.
People have really short attention spans. Realistically, reviews only
happen when people see the mail in their inbox and they have N minutes
to spare. After that point, your opportunity is essentially lost.
If a reviewer has a particular interest in a file or area, they may tag
it for later review. And then after a few days of working on something
else they come back and realize they have no time this week and delete
the series from their inbox so they don't feel bad about it over the
As a subsystem maintainer, the burden then falls upon me. And if
something has been collecting dust in patchwork for several weeks, there
is absolutely no chance that I or anybody else will get to it. I'm
reasonably sure that I'm the only person that ever visits the SCSI
patchwork with the intent to clear out the queue.
Consequently, the only way to revive interest is to resubmit. With a
comprehensive cover letter (which, incidentally, it would be nice if
patchwork would capture).
