2024-04-16ntfs3: serve as alias for the legacy ntfs driverChristian Brauner1-0/+9
Johan Hovold reported that removing the legacy ntfs driver broke boot for him since his fstab uses the legacy ntfs driver to access firmware from the original Windows partition. Use ntfs3 as an alias for legacy ntfs if CONFIG_NTFS_FS is selected. This is similar to how ext3 is treated.

2023-08-02fs: add CONFIG_BUFFER_HEADChristoph Hellwig1-0/+1
Add a new config option that controls building the buffer_head code, and select it from all file systems and stacking drivers that need it. For the block device nodes and alternative iomap based buffered I/O path is provided when buffer_head support is not enabled, and iomap needs a a small tweak to define the IOMAP_F_BUFFER_HEAD flag to 0 to not call into the buffer_head code when it doesn't exist. Otherwise this is just Kconfig and ifdef changes.

2023-01-26fs: build the legacy direct I/O code conditionallyChristoph Hellwig1-0/+1
Add a new LEGACY_DIRECT_IO config symbol that is only selected by the file systems that still use the legacy blockdev_direct_IO code, so that kernels without support for those file systems don't need to build the code.
