The patch titled export iov_shorten for ext4's use has been removed from the -mm tree. Its filename was export-iov_shorten-for-ext4s-use.patch This patch was dropped because it was merged into mainline or a subsystem tree The current -mm tree may be found at http://userweb.kernel.org/~akpm/mmotm/ ------------------------------------------------------ Subject: export iov_shorten for ext4's use From: Eric Sandeen <sandeen@xxxxxxxxxx> ext4 needs to deal with 2 different max file offsets for block- and extent-allocated file formats, whereas the s_maxbytes scheme can only deal with one. So, for block-allocated files, we must catch and fix up too-large offsets from within the filesystem. Having iov_shorten exported allows such things as: if (pos + length > sbi->s_bitmap_maxbytes) { nr_segs = iov_shorten((struct iovec *)iov, nr_segs, sbi->s_bitmap_maxbytes - pos); } to fix up too-large writes to these files in ext4_file_write().
