Hey Linus,
/* Summary */
This contains a few fixes for this cycle:
- Fix two memory leaks in pidfs.
- Prevent changing the idmapping of an already idmapped mount without
OPEN_TREE_CLONE through open_tree_attr().
- Don't fail listing extended attributes in kernfs when no extended
attributes are set.
- Fix the return value in coredump_parse().
- Fix the error handling for unbuffered writes in netfs.
- Fix broken data integrity guarantees for O_SYNC writes via iomap.
- Fix UAF in __mark_inode_dirty().
- Keep inode->i_blkbits constant in fuse.
- Fix coredump selftests.
- Fix get_unused_fd_flags() usage in do_handle_open().
- Rename EXPORT_SYMBOL_GPL_FOR_MODULES to EXPORT_SYMBOL_FOR_MODULES.
- Fix use-after-free in bh_read().
- Fix incorrect lflags value in the move_mount() syscall.
