[$] Removing read-only transparent huge pages for the page cache
Things do not always go the way kernel developers think they will. When the kernel gained support for the creation of read-only transparent huge pages for the page cache in 2019, [...]

New article: Inside the XFS Filesystem.
It splits the disk into independent Allocation Groups so multiple cores can work in parallel without blocking each other.
XFS uses B+ trees for almost everything. Check it out here: https://internals-for-interns.com/posts/xfs-filesystem/
In the previous article , we explored NTFSβa filesystem where everything is a file, from your documents to the Master File Table itself. NTFS centralized all metadata into the MFT, using attribute-based records and a single journal to keep Windows volumes consistent and feature-rich. Now let me introduce you to XFS, the filesystem designed for extreme scale. Originally built by Silicon Graphics in 1993 for their high-end IRIX workstations, XFS was engineered to handle filesystems measured in terabytes when most systems still counted in megabytes. Its core idea is to divide the disk into independent regions called Allocation Groupsβeach with its own free space tracking, its own inode management, and its own locks. This simple design choice is what allows XFS to scale linearly with the number of CPU cores and support filesystems up to 8 exabytes.

Linux kernel added many more incompatible feature bits in xfs file system superblock since last I worked, lets upstream same to HaikuOS.

XFS on HaikuOS
Not major functionality changes or bug fixes anymore(All critical ones are already fixed π) but a little bit of code refactoring.
- I found that every directory headers prefixes with Extent which is wrong, extents are basically what blockRun is in BFS so removed those prefix.
- Renamed Extent.cpp file to BlockDirectory.cpp since it implements block directory functionality.
