Currently, ext2fs is only implemented in Linux but - will soon be part of Gnu Hurd and of Masix. - -Changes from version 0.4b to version 0.5 -======================================== - - New superblock fields: s_lastcheck and s_checkinterval added - by Uwe Ohse <uwe@tirka.gun.de> to implement timedependent checks - of the file system - - Real random numbers for secure rm added by Pierre del Perugia - <delperug@gla.ecoledoc.ibp.fr> - - The mount warnings related to the state of a fs are not printed - if the fs is mounted read-only, idea by Nick Holloway - <alfie@dcs.warwick.ac.uk> - -Changes from version 0.4a to version 0.4b -========================================= - - Copyrights changed to include the name of my laboratory. - - Clean up of balloc.c and ialloc.c. - - More consistency checks. - - Block preallocation added by Stephen Tweedie. - - Direct reads of directories disallowed. - - Readahead implemented in readdir by Stephen Tweedie. - - Bugs in block and inodes allocation fixed. - - Readahead implemented in ext2_find_entry by Chip Salzenberg. - - New mount options: - `check=none|normal|strict' - `debug' - `errors=continue|remount-ro|panic' - `grpid', `bsdgroups' - `nocheck' - `nogrpid', `sysvgroups' - - truncate() now tries to deallocate contiguous blocks in a single call - to ext2_free_blocks(). - - lots of cosmetic changes. - -Changes from version 0.4 to version 0.4a -======================================== - - the `sync' option support is now complete. Version 0.4 was not - supporting it when truncating a file. I have tested the synchronous - writes and they work but they make the system very slow :-( I have - to work again on this to make it faster. - - when detecting an error on a mounted filesystem, version 0.4 used - to try to write a flag in the super block even if the filesystem had - been mounted read-only. This is fixed. - - the `sb=#' option now causes the kernel code to use the filesystem - descriptors located at block #+1. Version 0.4 used the superblock - backup located at block # but used the main copy of the descriptors. - - a new file attribute `S' is supported. This attribute causes - synchronous writes but is applied to a file not to the entire file - system (thanks to Michael Kraehe <kraehe@bakunin.north.de> for - suggesting it). - - the directory cache is inhibited by default. The cache management - code seems to be buggy and I have to look at it carefully before - using it again. - - deleting a file with the `s' attribute (secure deletion) causes its - blocks to be overwritten with random values not with zeros (thanks to - Michael A. Griffith <grif@cs.ucr.edu> for suggesting it). - - lots of cosmetic changes have been made. - -Changes from version 0.3 to version 0.4 -======================================= - - Three new mount options are supported: `check', `sync' and `sb=#'. - `check' tells the kernel code to make more consistency checks - when the file system is mounted. Currently, the kernel code checks - that the blocks and inodes bitmaps are consistent with the free - blocks and inodes counts. More checks will be added in future - releases. - `sync' tells the kernel code to use synchronous writes when updating - an inode, a bitmap, a directory entry or an indirect block. This - can make the file system much slower but can be a big win for files - recovery in case of a crash (and we can now say to the BSD folks - that Linux also supports synchronous updates :-). - `sb=#' tells the kernel code to use an alternate super block instead - of its master copy. `#' is the number of the block (counted in - 1024 bytes blocks) which contains the alternate super block. - An ext2 file system typically contains backups of the super block - at blocks 8193, 16385, and so on. - - I have change the meaning of the valid flag used by e2fsck. it - now contains the state of the file system. If the kernel code - detects an inconsistency while the file system is mounted, it flags - it as erroneous and e2fsck will detect that on next run. - - The super block now contains a mount counter. This counter is - incremented each time the file system is mounted read/write. When - this counter becomes bigger than a maximal mount counts (also stored - in the super block), e2fsck checks the file system, even if it had - been unmounted cleanly, and resets this counter to 0. - - File attributes are now supported. One can associate a set of - attributes to a file. Three attributes are defined: - `c': the file is marked for automatic compression, - `s': the file is marked for secure deletion: when the file is - deleted, its blocks are zeroed and written back to the disk, - `u': the file is marked for undeletion: when the file is deleted, - its contents are saved to allow a future undeletion. - Currently, only the `s' attribute is implemented in the kernel - code. Support for the other attributes will be added in a future - release. - - a few bugs related to times updates have been fixed by Bruce - Evans and me. - - a bug related to the links count of deleted inodes has been fixed. - Previous versions used to keep the links count set to 1 when a file - was deleted. The new version now sets links_count to 0 when deleting - the last link. - - a race condition when deallocating an inode has been fixed by - Stephen Tweedie. - diff --git a/fs/ext2/balloc.c b/fs/ext2/balloc.c index 6591abef64d0..bb6908066494 100644 --- a/fs/ext2/balloc.c +++ b/fs/ext2/balloc.c @@ -624,76 +624,3 @@ unsigned long ext2_bg_num_gdb(struct super_block *sb, int group) return EXT2_SB(sb)->s_gdb_count;
