ext2: Remove LEGACY_DIRECT_IO dependencycommit fb5de4358e1a ("ext2: Move direct-io to use iomap"), convertedext2 direct-io to iomap which killed the call to blockdev_direct_IO().So let's remove LEGACY_DIRECT_IO config dependency from ext2 Kconfig.Signed-off-by: Ritesh Harjani (IBM) Signed-off-by: Jan Kara Message-Id: List of files: /linux-6.15/fs/ext2/Kconfig

925c86a1 - fs: add CONFIG_BUFFER_HEAD

Tue, 01 Aug 2023 17:22:01 +0000

fs: add CONFIG_BUFFER_HEADAdd a new config option that controls building the buffer_head code, andselect it from all file systems and stacking drivers that need it.For the block device nodes and alternative iomap based buffered I/O pathis provided when buffer_head support is not enabled, and iomap needs aa small tweak to define the IOMAP_F_BUFFER_HEAD flag to 0 to not callinto the buffer_head code when it doesn't exist.Otherwise this is just Kconfig and ifdef changes.Signed-off-by: Christoph Hellwig Reviewed-by: Luis Chamberlain Reviewed-by: Johannes Thumshirn Link: https://lore.kernel.org/r/20230801172201.1923299-7-hch@lst.deSigned-off-by: Jens Axboe List of files: /linux-6.15/fs/ext2/Kconfig

fs: build the legacy direct I/O code conditionallyAdd a new LEGACY_DIRECT_IO config symbol that is only selected by thefile systems that still use the legacy blockdev_direct_IO code, so thatkernels without support for those file systems don't need to build thecode.Signed-off-by: Christoph Hellwig Reviewed-by: Jan Kara Reviewed-by: Eric Biggers Link: https://lore.kernel.org/r/20230125065839.191256-3-hch@lst.deSigned-off-by: Jens Axboe List of files: /linux-6.15/fs/ext2/Kconfig

8b1e7076 - ext2: use iomap_fiemap to implement ->fiemap

Tue, 20 Jul 2021 13:33:39 +0000

ext2: use iomap_fiemap to implement ->fiemapSwitch from generic_block_fiemap to use the iomap version. The onlyinteresting part is that ext2_get_blocks gets confused when beingasked for overly long ranges, so copy over the limit to the inodesize from generic_block_fiemap into ext2_fiemap.Link: https://lore.kernel.org/r/20210720133341.405438-3-hch@lst.deSigned-off-by: Christoph Hellwig Signed-off-by: Jan Kara List of files: /linux-6.15/fs/ext2/Kconfig
