From: Dave Chinner Date: Mon, 14 Dec 2009 23:11:57 +0000 (+0000) Subject: XFS: Free buffer pages array unconditionally X-Git-Tag: v2.6.33-rc1~41^2 X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=3fc98b1ac036675b95f6e3fafd5ef147b97d4d30;p=pandora-kernel.git XFS: Free buffer pages array unconditionally The code in xfs_free_buf() only attempts to free the b_pages array if the buffer is a page cache backed or page allocated buffer. The extra log buffer that is used when the log wraps uses pages that are allocated to a different log buffer, but it still has a b_pages array allocated when those pages are associated to with the extra buffer in xfs_buf_associate_memory. Hence we need to always attempt to free the b_pages array when tearing down a buffer, not just on buffers that are explicitly marked as page bearing buffers. This fixes a leak detected by the kernel memory leak code. Signed-off-by: Dave Chinner Signed-off-by: Alex Elder --- Reading git-diff-tree failed
