There\u0027s\nactually a library function in include/linux/highmem.h that does exactly\nthat, but it\u0027s confusingly named memclear_highpage_flush(), which is\ndescriptive of *how* it does the work rather than what the *purpose* is.\nSo this patchset renames the function to zero_user_page(), and calls it\nfrom the various places that currently open code it.\n\nThis first patch introduces the new function call, and converts all the\ncore kernel callsites, both the open-coded ones and the old\nmemclear_highpage_flush() ones.

      "message": "[PATCH] xip: reduce code duplication\n\nThis patch reworks filemap_xip.c with the goal to reduce code duplication\nfrom mm/filemap.c.  It applies agains 2.6.12-rc6-mm1.  Instead of\nimplementing the aio functions, this one implements the synchronous\nread/write functions only.  For readv and writev, the generic fallback is\nused.  For aio, we rely on the application doing the fallback.  Since our\n\"synchronous\" function does memcpy immediately anyway, there is no\nperformance difference between using the fallbacks or implementing each\noperation.\n\nSigned-off-by: Carsten Otte \u003ccotte@de.ibm.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n"
