2009-12-10exofs: move osd.c to ios.cBoaz Harrosh
If I do a "git mv" together with a massive code change and commit in one patch, git looses the rename and records a delete/new instead. This is bad because I want a rename recorded so later rebased/cherry-picked patches to the old name will work. Also the --follow is lost. Signed-off-by: Boaz Harrosh <bharrosh@panasas.com>
2009-03-31exofs: super_operations and file_system_typeBoaz Harrosh
This patch ties all operation vectors into a file system superblock and registers the exofs file_system_type at module's load time. * The file system control block (AKA on-disk superblock) resides in an object with a special ID (defined in common.h). Information included in the file system control block is used to fill the in-memory superblock structure at mount time. This object is created before the file system is used by mkexofs.c It contains information such as: - The file system's magic number - The next inode number to be allocated Signed-off-by: Boaz Harrosh <bharrosh@panasas.com>
2009-03-31exofs: dir_inode and directory operationsBoaz Harrosh
implementation of directory and inode operations. * A directory is treated as a file, and essentially contains a list of <file name, inode #> pairs for files that are found in that directory. The object IDs correspond to the files' inode numbers and are allocated using a 64bit incrementing global counter. * Each file's control block (AKA on-disk inode) is stored in its object's attributes. This applies to both regular files and other types (directories, device files, symlinks, etc.). Signed-off-by: Boaz Harrosh <bharrosh@panasas.com>
2009-03-31exofs: symlink_inode and fast_symlink_inode operationsBoaz Harrosh
Generic implementation of symlink ops. Signed-off-by: Boaz Harrosh <bharrosh@panasas.com>
2009-03-31exofs: file and file_inode operationsBoaz Harrosh
implementation of the file_operations and inode_operations for regular data files. Most file_operations are generic vfs implementations except: - exofs_truncate will truncate the OSD object as well - Generic file_fsync is not good for none_bd devices so open code it - The default for .flush in Linux is todo nothing so call exofs_fsync on the file.

2009-03-31exofs: Kbuild, Headers and osd utilsBoaz Harrosh
This patch includes osd infrastructure that will be used later by the file system. Also the declarations of constants, on disk structures, and prototypes. And the Kbuild+Kconfig files needed to build the exofs module. Signed-off-by: Boaz Harrosh <bharrosh@panasas.com>
