Convert content from the ext4 wiki to Documentation rst files so it is

And the usual bug fixes and cleanups, including a Spectre gadget fixup and some hardening against maliciously corrupted file systems. -----BEGIN PGP SIGNATURE----- iQEzBAABCAAdFiEEK2m5VNv+CHkogTfJ8vlZVpUNgaMFAltx3CAACgkQ8vlZVpUN gaOfkAgApkNU46yPWWFqJpeTR76Go4zW00x9Piaita+KpQcTCUokK0BDXXeydOEo zhtNjCRl00vbhnYJ90T75Y3ce9oGQDkWpXHFZBdl+kmMBaIHQJYEECCLR2zrvxVk LhsixvLozQd/VFenwzmXLqYshiZjhjBZOKo7/xsoy4waer1vNidA9/SR3hGWTMOk 9IsEVqw1h6pZt7ZB/leZmZ348H9QZZbYOUWl2ArvdmNeg2t8pWH0MD0bos+mj5lW xihyJEIS/OjWZRJhM2WEPMO7U4jD/aX3zmDMGePp/vC5KSqA4FGwk671xIyD+LXR Hd8Rn8chRe4/iyhBqHpJNkqHQRUV6g== =SA3p -----END PGP SIGNATURE----- Merge tag 'ext4_for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tytso/ext4 Pull ext4 updates from Ted Ts'o: - Convert content from the ext4 wiki to Documentation rst files so it is more likely to be updated as we add new features to ext4. - Add 64-bit timestamp support to ext4's superblock fields. - ... and the usual bug fixes and cleanups, including a Spectre gadget fixup and some hardening against maliciously corrupted file systems. * tag 'ext4_for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tytso/ext4: (34 commits) ext4: remove unneeded variable "err" in ext4_mb_release_inode_pa() ext4: improve code readability in ext4_iget() ext4: fix spectre gadget in ext4_mb_regular_allocator() ext4: check for NUL characters in extended attribute's name ext4: use ext4_warning() for sb_getblk failure ext4: fix race when setting the bitmap corrupted flag ext4: reset error code in ext4_find_entry in fallback ext4: handle layout changes to pinned DAX mappings dax: dax_layout_busy_page() warn on !exceptional docs: fix up the obviously obsolete bits in the new ext4 documentation docs: add new ext4 superblock time extension fields docs: create filesystem internal section ext4: use swap macro in mext_page_double_lock ext4: check allocation failure when duplicating "data" in ext4_remount() ext4: fix warning message in ext4_enable_quotas() ext4: super: extend timestamps to 40 bits jbd2: replace current_kernel_time64 with ktime equivalent ext4: use timespec64 for all inode times ext4: use ktime_get_real_seconds for i_dtime ext4: use 64-bit timestamps for mmp_time ...
