[patch 0/2] xfs: xfs_tosspages() bug

[adahl@xxxxxxx]

Hi everyone,

This patch set fixes a bug in xfs with the xfs_tosspages() function and adds a 
tosspages test to xfstests.

xfs_tosspages() tries to avoid tossing a partial tail page, but it gets the 
calculation wrong.  As a result, if we pass in an interval [0, PAGE-SIZE-1] we 
end up tossing all pages.  This patch set resolves this issue.

Thanks,

Andrew
