Alessio - you can remove the "hardware donation from CELF" line after the first submission or so. It doesn't need to be on every submission of the patch set, and it doesn't need to go into the commit message for the patch set. We only want it associated with the patch set somewhere Google-able (like LKML). That said, I can answer Greg's question. This is to speed up the symbol resolution on module loading. The last numbers I saw showed a reduction of about 15-20% for the module load time, for large-ish modules. Of course this is highly dependent on the size of the modules, what they do at load time, and how many symbols are looked up to link them into the kernel. Alessio - do you have any timings you can share for the speedup? -- Tim ============================= Tim Bird Architecture Group Chair, CE Workgroup of the Linux Foundation Senior Staff Engineer, Sony Network Entertainment ============================= -- To unsubscribe from this list: send the line "unsubscribe linux-embedded" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
