-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 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 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)

-   - 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
