From beaec07ba6af35d387643b76a2920a7a6e22207b Mon Sep 17 00:00:00 2001 From: Boaz Harrosh Date: Mon, 27 Oct 2008 19:31:34 +0200 Subject: exofs: address_space_operations OK Now we start to read and write from osd-objects. We try to collect at most contiguous pages as possible in a single write/read. The first page index is the object's offset. TODO: In 64-bit a single bio can carry at most 128 pages. Add support of chaining multiple bios Signed-off-by: Boaz Harrosh --- fs/exofs/exofs.h | 6 ++++++ 1 file changed, 6 insertions(+) (limited to 'fs/exofs/exofs.h') diff --git a/fs/exofs/exofs.h b/fs/exofs/exofs.h index 825454d76f6c..0276242326ab 100644 --- a/fs/exofs/exofs.h +++ b/fs/exofs/exofs.h @@ -130,6 +130,9 @@ static inline struct exofs_i_info *exofs_i(struct inode *inode) /* inode.c */ void exofs_truncate(struct inode *inode); int exofs_setattr(struct dentry *, struct iattr *); +int exofs_write_begin(struct file *file, struct address_space *mapping, + loff_t pos, unsigned len, unsigned flags, + struct page **pagep, void **fsdata); /********************* * operation vectors * @@ -138,6 +141,9 @@ int exofs_setattr(struct dentry *, struct iattr *); extern const struct inode_operations exofs_file_inode_operations; extern const struct file_operations exofs_file_operations; +/* inode.c */ +extern const struct address_space_operations exofs_aops; + /* symlink.c */ extern const struct inode_operations exofs_symlink_inode_operations; extern const struct inode_operations exofs_fast_symlink_inode_operations; -- cgit v1.2.1
