From c3fe493ccdb1f443c30155150391835004014c6a Mon Sep 17 00:00:00 2001 From: Fabian Frederick Date: Thu, 15 Sep 2016 11:52:07 -0400 Subject: ext4: remove unneeded test in ext4_alloc_file_blocks() ext4_alloc_file_blocks() is called from ext4_zero_range() and ext4_fallocate() both already testing EXT4_INODE_EXTENTS We can call ext_depth(inode) unconditionnally. [ Added BUG_ON check to make sure ext4_alloc_file_blocks() won't get called for a indirect-mapped inode in the future. -- tytso ] Signed-off-by: Fabian Frederick Signed-off-by: Theodore Ts'o --- fs/ext4/extents.c | 9 ++------- 1 file changed, 2 insertions(+), 7 deletions(-) diff --git a/fs/ext4/extents.c b/fs/ext4/extents.c index 7f69347bd5a5..ef288558b869 100644 --- a/fs/ext4/extents.c +++ b/fs/ext4/extents.c @@ -4679,6 +4679,7 @@ static int ext4_alloc_file_blocks(struct file *file, ext4_lblk_t offset, unsigned int credits; loff_t epos; + BUG_ON(!ext4_test_inode_flag(inode, EXT4_INODE_EXTENTS)); map.m_lblk = offset; map.m_len = len; /* @@ -4693,13 +4694,7 @@ static int ext4_alloc_file_blocks(struct file *file, ext4_lblk_t offset, * credits to insert 1 extent into extent tree */ credits = ext4_chunk_trans_blocks(inode, len); - /* - * We can only call ext_depth() on extent based inodes - */ - if (ext4_test_inode_flag(inode, EXT4_INODE_EXTENTS)) - depth = ext_depth(inode); - else - depth = -1; + depth = ext_depth(inode); retry: while (ret >= 0 && len) { -- cgit v1.2.1
