From 518f167a37b3c53f3cf44d27800455ca24e920f6 Mon Sep 17 00:00:00 2001 From: Boaz Harrosh Date: Thu, 21 Jan 2010 20:00:02 +0200 Subject: [PATCH] exofs: Micro-optimize exofs_i_info optimize the exofs_i_info struct usage by moving the embedded vfs_inode to be first. A compiler might optimize away an "add" operation with constant zero. (Which it cannot with other constants) Signed-off-by: Boaz Harrosh --- fs/exofs/exofs.h | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/fs/exofs/exofs.h b/fs/exofs/exofs.h index c35fd4623986..13663da2b119 100644 --- a/fs/exofs/exofs.h +++ b/fs/exofs/exofs.h @@ -78,13 +78,13 @@ struct exofs_sb_info { * our extension to the in-memory inode */ struct exofs_i_info { + struct inode vfs_inode; /* normal in-memory inode */ + wait_queue_head_t i_wq; /* wait queue for inode */ unsigned long i_flags; /* various atomic flags */ uint32_t i_data[EXOFS_IDATA];/*short symlink names and device #s*/ uint32_t i_dir_start_lookup; /* which page to start lookup */ - wait_queue_head_t i_wq; /* wait queue for inode */ uint64_t i_commit_size; /* the object's written length */ uint8_t i_cred[OSD_CAP_LEN];/* all-powerful credential */ - struct inode vfs_inode; /* normal in-memory inode */ }; static inline osd_id exofs_oi_objno(struct exofs_i_info *oi) -- 2.20.1
