Maybe it's a matter of filesystem or some other quirk. It seems easy for you to reproduce it, so would you mind bisecting it? Should be fairly straightforward; I'd start at commit "xarray: Add MAINTAINERS entry", since the page cache shouldn't be affected by anything up to that point, then bisect forwards from there. > BTW, for my convenience, do you have these patches in a public git tree? I didn't publish it; it's hard to push out a tree based on linux-next. I'll try to make that happen. ------------------------------------------------------------------------------ Check out the vibrant tech community on one of the world's most engaging tech sites, Slashdot.org! http://sdm.link/slashdot
