Many struct inode_operations in the kernel can be "const". Marking them const moves these to the .rodata section, which avoids false sharing with potential dirty data. In addition it'll catch accidental writes at compile time to these shared resources. Signed-off-by:

This morning I needed to read a Minix V3 filesystem, but unfortunately my 2.6.19 did not support that, and neither did the downloaded 2.6.20rc4. Fortunately, google told me that Daniel Aragones had already done the work, patch found at http://www.terra.es/personal2/danarag/ Unfortunaly, looking at the patch was painful to my eyes, so I polished it a bit before applying. The resulting kernel boots, and reads the filesystem it needed to read. Signed-off-by:

This is a conversion to make the various file_operations structs in fs/ const. Basically a regexp job, with a few manual fixups The goal is both to increase correctness (harder to accidentally write to shared datastructures) and reducing the false sharing of cachelines with things that get dirty in .data (while .rodata is nicely read only and thus cache clean) Signed-off-by:

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
