It takes the position where to\n        start and end the zeroing which avoids length calculations and\n\tmakes code clearer.\n\nzero_user_segment(page, start, end)\n\n        Same for a single segment.\n\nzero_user(page, start, length)\n\n        Length variant for the case where we know the length.\n\nWe remove the zero_user_page macro. Issues:\n\n1. Its a macro. Inline functions are preferable.\n\n2. The KM_USER0 macro is only defined for HIGHMEM.\n\n   Having to treat this special case everywhere makes the\n   code needlessly complex. The parameter for zeroing is always\n   KM_USER0 except in one single case that we open code.\n\nAvoiding KM_USER0 makes a lot of code not having to be dealing\nwith the special casing for HIGHMEM anymore. Dealing with\nkmap is only necessary for HIGHMEM configurations. In those\nconfigurations we use KM_USER0 like we do for a series of other\nfunctions defined in highmem.h.\n\nSince KM_USER0 is depends on HIGHMEM the existing zero_user_page\nfunction could not be a macro. zero_user_* functions introduced\nhere can be be inline because that constant is not used when these\nfunctions are called.\n\nAlso extract the flushing of the caches to be outside of the kmap.\n\n[akpm@linux-foundation.org: fix nfs and ntfs build]\n[akpm@linux-foundation.org: fix ntfs build some more]\nSigned-off-by: Christoph Lameter \u003cclameter@sgi.com\u003e\nCc: Steven French \u003csfrench@us.ibm.com\u003e\nCc: Michael Halcrow \u003cmhalcrow@us.ibm.com\u003e\nCc: \u003clinux-ext4@vger.kernel.org\u003e\nCc: Steven Whitehouse \u003cswhiteho@redhat.com\u003e\nCc: Trond Myklebust \u003ctrond.myklebust@fys.uio.no\u003e\nCc: \"J.

      "message": "ocfs2: teach extend/truncate about sparse files\n\nFor ocfs2_truncate_file(), we eliminate the \"simple\" truncate case which no\nlonger exists since i_size is not tied to i_clusters. In\nocfs2_extend_file(), we skip the allocation / page zeroing code for file\nsystems which understand sparse files.\n\nThe core truncate code is changed to do a bottom up tree traversal. This\ngets abstracted out into it\u0027s own function. To make things more readable,\nmost of the special case handling for in-inode extents from\nocfs2_do_truncate() is also removed.\n\nThough write support for sparse files comes in a later patch, we at least\nupdate ocfs2_prepare_inode_for_write() to skip allocation for sparse files.\n\nSigned-off-by: Mark Fasheh \u003cmark.fasheh@oracle.com\u003e\n"
