From 5d3851530d6d68564e4e0ce04d0547d4d106fc72 Mon Sep 17 00:00:00 2001 From: Joe Perches Date: Mon, 28 Nov 2011 10:40:46 -0800 Subject: 9p: Reduce object size with CONFIG_NET_9P_DEBUG Reduce object size by deduplicating formats. Use vsprintf extension %pV. Rename P9_DPRINTK uses to p9_debug, align arguments. Add function for _p9_debug and macro to add __func__. Add missing "\n"s to p9_debug uses. Remove embedded function names as p9_debug adds it. Remove P9_EPRINTK macro and convert use to pr_. Add and use pr_fmt and pr_. $ size fs/9p/built-in.o* text data bss dec hex filename 62133 984 16000 79117 1350d fs/9p/built-in.o.new 67342 984 16928 85254 14d06 fs/9p/built-in.o.old $ size net/9p/built-in.o* text data bss dec hex filename 88792 4148 22024 114964 1c114 net/9p/built-in.o.new 94072 4148 23232 121452 1da6c net/9p/built-in.o.old Signed-off-by: Joe Perches Signed-off-by: Eric Van Hensbergen --- fs/9p/vfs_addr.c | 13 ++++++------- 1 file changed, 6 insertions(+), 7 deletions(-) (limited to 'fs/9p/vfs_addr.c') diff --git a/fs/9p/vfs_addr.c b/fs/9p/vfs_addr.c index 2524e4c..0ad61c6 100644 --- a/fs/9p/vfs_addr.c +++ b/fs/9p/vfs_addr.c @@ -56,7 +56,7 @@ static int v9fs_fid_readpage(struct p9_fid *fid, struct page *page) struct inode *inode; inode = page->mapping->host; - P9_DPRINTK(P9_DEBUG_VFS, "\n"); + p9_debug(P9_DEBUG_VFS, "\n"); BUG_ON(!PageLocked(page)); @@ -116,14 +116,14 @@ static int v9fs_vfs_readpages(struct file *filp, struct address_space *mapping, struct inode *inode; inode = mapping->host; - P9_DPRINTK(P9_DEBUG_VFS, "inode: %p file: %p\n", inode, filp); + p9_debug(P9_DEBUG_VFS, "inode: %p file: %p\n", inode, filp); ret = v9fs_readpages_from_fscache(inode, mapping, pages, &nr_pages); if (ret == 0) return ret; ret = read_cache_pages(mapping, pages, (void *)v9fs_vfs_readpage, filp); - P9_DPRINTK(P9_DEBUG_VFS, " = %d\n", ret); + p9_debug(P9_DEBUG_VFS, " = %d\n", ret); return ret; } @@ -263,10 +263,9 @@ v9fs_direct_IO(int rw, struct kiocb *iocb, const struct iovec *iov, * Now that we do caching with cache mode enabled, We need * to support direct IO */ - P9_DPRINTK(P9_DEBUG_VFS, "v9fs_direct_IO: v9fs_direct_IO (%s) " - "off/no(%lld/%lu) EINVAL\n", - iocb->ki_filp->f_path.dentry->d_name.name, - (long long) pos, nr_segs); + p9_debug(P9_DEBUG_VFS, "v9fs_direct_IO: v9fs_direct_IO (%s) off/no(%lld/%lu) EINVAL\n", + iocb->ki_filp->f_path.dentry->d_name.name, + (long long)pos, nr_segs); return -EINVAL; } -- cgit v1.1
