- Fix online fsck to handle inode btrees correctly on 64k block filesystems. - Teach online fsck to check directory and attribute names for invalid characters. - Miscellanous fixes for online fsck. - Introduce a new panic mask so that we can halt immediately on metadata corruption (for debugging purposes) - Fix a block mapping race during writeback. - Cache unlinked inode list backrefs in memory to speed up list processing. - Separate the bnobt/cntbt and inobt/finobt buffer verifiers so that we can detect crosslinked btrees. - Refactor magic number verification so that we can standardize it. - Strengthen ondisk metadata structure offset build time verification. - Fix a memory corruption problem in the listxattr code. - Fix a shutdown problem during log recovery due to unreserved finobt expansion. - Fix a referential integrity problem where O_TMPFILE inodes were put on the unlinked list with nlink > 0 which would cause asserts during log recovery if the system went down immediately. - Refactor the delayed allocation allocator to be more clever about the possibility that its mapping might be stale. - Various fixes to the copy on write mechanism. - Make CoW preallocation suitable for use even with writes that wouldn't otherwise require it. - Refactor an internal API. - Fix some statx implementation bugs. - Fix miscellaneous compiler and static checker complaints. -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEEUzaAxoMeQq6m2jMV+H93GTRKtOsFAlx5ZaIACgkQ+H93GTRK tOvZnhAApQ7bEsJIovMhW36yh/pXef9iKk2xAv6Kwn9jWEysQH+vlBvwEnaJTb0E 8WBYm0Jv1DK8A6luSLmWbCIWB+RMkwhufXKadaTBtL8ySWq8uf776e9dVQflRyNU pN5k+JwQEfVDw8beAkUhr8yrZODv6iQi7/e2O0ARuf6CeNvX5ZR7OTjPdW3vX/zu F0t5UOegd2kGq+kkmIfDpAlQ8ju5U6P8sjImbXbjiTtSBydqkadgx3rCfa7MdD7u Y3Zauzba9PmJyJQ71JNsXgle58Ojq57LwWsRL/XEufy5B1upZsDzfDYTlAsDIkPJ pcG3YGPuGrBG/VX12XHmHqxt6DeW3S+GMVVxx7xBpSVDiSGeOazugLrAXk83NVzo eaUM96VVJO1lZArLxieZ7EBcuuNjW4PYYCOmUobGz/kxAzjubJU3dRMRLHiG5A1H TB2p0WlIP8cSxboF+SK8mhBmYDa1w16TCHQ6d6i9IFqcrmSc0JUvE3gy1UJzHhMb FESHasLTz9NTRhnCY3QjOYcT9Sa/s22+46+yZ8xBADG14N00dsYnCC5bbR/ALI09 9RNawcDvzN6p9pcJMuRImWlXx5dpNjIAr/bEp+xZK1tnsHg8HKHub61e2x6PhmH8 COJTErXV01IDRSVdQv6rFSE38/FACYppjzNyUdE7VydyKSoxBsM= =BAFq -----END PGP SIGNATURE----- Merge tag 'xfs-5.1-merge-4' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux Pull xfs updates from Darrick Wong: "Here are a number of new features and bug fixes for 5.1 They've undergone a week's worth of fstesting and merge cleanly with master as of this morning Most of the changes center on improving metadata validation and fixing problems with online fsck, though there's also a new cache to speed up unlinked inode handling and cleanup of the copy on write code in preparation for future features Changes for Linux 5.1: -
