Release February 15, 2002 (version 1.0.15)
This is our fifty-third release of IBM's Enterprise JFS technology port to Linux.
Beta 1 was release 0.1.0 on 12/8/2000, Beta 2 was release 0.2.0 on 3/7/2001,
Beta 3 was release 0.3.0 on 4/30/2001, and release 1.0.0 on 6/28/2001.
Function and Fixes in drop 53 (1.0.15)
- Fix trap when appending to very large file
- Moving jfs headers into fs/jfs at Linus' request
- Move up to linux-2.5.4
- Fix file size limit on 32-bit (Andi Kleen)
- make changelog more read-able and include only 1.0.0 and above (Christoph Hellwig)
- Don't allocate metadata pages from high memory. JFS keeps them kmapped too long causing deadlock.
- Fix xtree corruption when creating file with >= 64 GB of physically contiguous dasd
- Replace semaphore with struct completion for thread startup/shutdown (Benedikt Spranger)
- cleanup Tx alloc/free (Christoph Hellwig)
- Move up to linux-2.5.3
- thread cleanups (Christoph Hellwig)
- First step toward making tblocks and tlocks dynamically allocated. Intro tid_t and lid_t to
insulate the majority of the code from future changes. Also hide TxBlock and TxLock arrays
by using macros to get from tids and lids to real structures.
- minor list-handling cleanup (Christoph Hellwig)
- Replace altnext and altprev with struct list_head
- Clean up the debugging code and add support for collecting statistics (Christoph Hellwig)
Function and Fixes in drop 52 (1.0.14)
- Fix hang in invalidate_metapages when jfs.o is built as a module
- Fix anon_list removal logic in txLock
Function and Fixes in drop 51 (1.0.13)
- chmod changes on newly created directories are lost after umount (bug 2535)
- Page locking race fixes
- Improve metapage locking
- Fix timing window. Lock page while metapage is active to avoid page going
away before the metadata is released. (Fixed crash during mount/umount testing)
- Make changes for 2.5.2 kernel
- Fix race condition truncating large files
Function and Fixes in drop50 (1.0.12)
- Add O_DIRECT support
- Add support for 2.4.17 kernel
- Make sure COMMIT_STALE gets reset before the inode is unlocked. Fixing
this gets rid of XT_GETPAGE errors
- Remove invalid __exit keyword from metapage_exit and txExit.
- fix assert(log->cqueue.head == NULL by waiting longer
Function and Fixes in drop49 (1.0.11)
- Readdir was not handling multibyte codepages correctly.
- Make mount option parsing more robust.
- Add iocharset mount option.
- Journalling of symlinks incorrect, resulting in logredo failure of -265.
- Add jfsutils information to Changes file
- Improve recoverability of the file system when metadata corruption is detected.
- Fix kernel OOPS when root inode is corrupted
Function and Fixes in drop48 (1.0.10)
- put inodes later on hash queues
- Fix boundary case in xtTruncate
- When invalidating metadata, try to flush the dirty buffers rather than sync them.
- Add another sanity check to avoid trapping when imap is corrupt
- Fix file truncate while removing large file (assert(cmp == 0))
- read_cache_page returns ERR_PTR, not NULL on error
- Add dtSearchNode and dtRelocate
- JFS needs to use generic_file_open & generic_file_llseek
- Remove lazyQwait, etc. It created an unnecessary bottleneck in TxBegin.
Function and Fixes in drop47 (1.0.9)
- Fix data corruption problem when creating files while deleting others. (jitterbug 183)
- Make sure all metadata is written before finalizing the log
- Fix serialization problem in shutdown by setting i_size of directory sooner. (bugzilla #334)
- JFS should quit whining when special files are marked dirty during read-only mount.
- Must always check rc after DT_GETPAGE
- Add diExtendFS
- Removing defconfig form JFS source - not really needed
Function and Fixes in drop46 (1.0.8)
- Synclist was being built backwards causing logredo to quit too early
- jfs_compat.h needs to include module.h
- uncomment EXPORTS_NO_SYMBOLS in super.c
- Minor code cleanup
- xtree of zero-truncated file not being logged
- Fix logging on file truncate
- remove unused metapage fields
Function and Fixes in drop45 (1.0.7)
- cleanup remove IS_KIOBUFIO define.
- cleanup remove TRUNC_NO_TOSS define.
- have jFYI's use the name directly from dentry
- Remove nul _ALLOC and _FREE macros and also make spinlocks static.
- cleanup add externs where needed in the header files
- jfs_write_inode is a bad place to call iput. Also limit warnings.
- More truncate cleanup
- Truncate cleanup
- Add missing statics in jfs_metapage.c
- fsync fixes
- Clean up symlink code - use page_symlink_inode_operations
- unicode handling cleanup
- cleanup replace UniChar with wchar_t
- Get rid of CDLL_* macros - use list.h instead
- 2.4.11-prex mount problem Call new_inode instead of get_empty_inode
- use kernel min/max macros
- Add MODULE_LICENSE stub for older kernels
- IA64/gcc3 fixes
- Log Manager fixes, introduce __SLEEP_COND macro
- Mark superblock dirty when some errors detected (forcing fsck to be run).
- More robust remounting from r/o to r/w.
- Misc. cleanup add static where appropriate
- small cleanup in jfs_umount_rw
- add MODULE_ stuff
- Set *dropped_lock in alloc_metapage
- Get rid of unused log list
- cleanup jfs_imap.c to remove _OLD_STUFF and _NO_MORE_MOUNT_INODE defines
- Log manager cleanup
- Transaction manager cleanup
- correct memory allocations flags
- Better handling of iterative truncation
- Change continue to break, otherwise we don't re-acquire LAZY_LOCK
Function and Fixes in drop44 (1.0.6)
- Create jfs_incore.h which merges linux/jfs_fs.h, linux/jfs_fs_i.h, and jfs_fs_sb.h
- Create a configuration option to handle JFS_DEBUG define
- Fixed a few cases where positive error codes were returned to the VFS.
- Replace jfs_dir_read by generic_read_dir.
- jfs_fsync_inode is only called by jfs_fsync_file, merge the two and rename to jfs_fsync.
- Add a bunch of missing externs.
- jfs_rwlock_lock is unused, nuke it.
- Always use atomic set/test_bit operations to protect jfs_ip->cflag
- Combine jfs_ip->flag with jfs_ip->cflag
- Fixed minor format errors reported by fsck
- cflags should be long so bitops always works correctly
- Use GFP_NOFS for runtime memory allocations
- Support VM changes in 2.4.10 of the kernel
- Remove ifdefs supporting older 2.4 kernels. JFS now requires at least 2.4.3 or 2.4.2-ac2
- Simplify and remove one use of IWRITE_TRYLOCK
- jfs_truncate was not passing tid to xtTruncate
- removed obsolete extent_page workaround
- correct recovery from failed diAlloc call (disk full)
- In write_metapage, don't call commit_write if prepare_write failed

- Fix error message in jfs_strtoUCS
Function and Fixes in drop41 (1.0.3)
- Patch to move from previous release to latest release needs to update the version number in super.c
- Jitterbug problems (134,140,152) removing files have been fixed
- Set rc=ENOSPC if ialloc fails in jfs_create and jfs_mkdir
- Fixed jfs_txnmgr.c 775! assert
- Fixed jfs_txnmgr.c 884! assert(mp->nohomeok==0)

- Fail more gracefully in jfs_imap.c
- Print more information when char2uni fails
- Fix timing problem between Block map and metapage cache - jitterbug 139
