minix: Add required sanity checking to minix_check_superblock()

2026-03-04T12:19:31Z

[ Upstream commit 8c97a6ddc95690a938ded44b4e3202f03f15078c ] The fs/minix implementation of the minix filesystem does not currently support any other value for s_log_zone_size than 0. This is also the only value supported in util-linux; see mkfs.minix.c line 511. In addition, this patch adds some sanity checking for the other minix superblock fields, and moves the minix_blocks_needed() checks for the zmap and imap also to minix_check_super_block(). This also closes a related syzbot bug report.

fs: change write_begin/write_end interface to take struct kiocb *

2025-07-16T12:48:18Z

Change the address_space_operations callbacks write_begin() and write_end() to take struct kiocb * as the first argument instead of struct file *. Update all affected function prototypes, implementations, call sites, and related documentation across VFS, filesystems, and block layer. Part of a series refactoring address_space_operations write_begin and write_end callbacks to use struct kiocb for passing write context and flags.

minix: remove SLAB_MEM_SPREAD flag usage

2024-02-27T10:21:32Z

The SLAB_MEM_SPREAD flag used to be implemented in SLAB, which was removed as of v6.8-rc1 (see [1]), so it became a dead flag since the commit 16a1d968358a ("mm/slab: remove mm/slab.c and slab_def.h"). And the series[1] went on to mark it obsolete explicitly to avoid confusion for users. Here we can just remove all its users, which has no any functional change.
