Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it.

JFS: ext2 inode attributes for jfs ext2 inode attributes with relevance for jfs: 'a' EXT2_APPEND_FL -> append only 'i' EXT2_IMMUTABLE_FL -> immutable file 's' EXT2_SECRM_FL -> zero file 'u' EXT2_UNRM_FL -> allow for unrm 'A' EXT2_NOATIME_FL -> no access time 'D' EXT2_DIRSYNC_FL -> dirsync 'S' EXT2_SYNC_FL -> sync overview of jfs flags (partially for OS/2) value (OS/2) Linux ext2 attrs ------------------------------------------------ 0x00010000 IFJOURNAL - 0x00020000 ISPARSE used 0x00040000 INLINEEA used 0x00080000 - - JFS_NOATIME_FL 0x00100000 - - JFS_DIRSYNC_FL 0x00200000 - - JFS_SYNC_FL 0x00400000 - - JFS_SECRM_FL 0x00800000 ISWAPFILE - JFS_UNRM_FL 0x01000000 - - JFS_APPEND_FL 0x02000000 IREADONLY - JFS_IMMUTABLE_FL 0x04000000 IHIDDEN - - 0x08000000 ISYSTEM - - 0x10000000 - - 0x20000000 IDIRECTORY used 0x40000000 IARCHIVE - 0x80000000 INEWNAME - the implementation is straight forward, except for the fact that the attributes have to be mapped to match with the ext2 ones to avoid a separate tool for manipulating them (this could be avoided when using a separate flag field in the on-disk representation, but the overhead is minimal) a special jfs_ioctl is added to allow for the new JFS_IOC_GETFLAGS and JFS_IOC_SETFLAGS calls. a helper function jfs_set_inode_flags() to transfer the flags from the on-disk version to the inode minor changes to allow flag inheritance on inode creation, as well as a cleanup of the on-disk flags (including the new ones) beforementioned helper to map between ext2 and jfs versions of the new flags ... the JFS_SECRM_FL and JFS_UNRM_FL are not done yet and I'm not 100% sure they are worth the effort, the rest seems to work out of the box ...
