Subject: [GIT PULL] hfs/hfsplus changes for 7.0-rc1

Hello Linus,

This pull request contains several fixes of syzbot reported
issues and HFS+ fixes of xfstests failures.

Jori Koolstra has fixed the syzbot reported issue of triggering
BUG_ON() in the case of corrupted superblock. This patch replaces
the BUG_ON() in multiple places with proper error handling and
resolves the syzbot reported bug.

Mehdi Ben Hadj Khelifa has fixed the syzbot reported issues in
mount logic of HFS/HFS+ file systems. When HFS/HFS+ were converted to
the new mount api a bug was introduced by changing the allocation
pattern of sb->s_fs_info. The memory leaks issue has been fixed
by these two patches.

Shardul Bankar suggested the nice fix in hfs_bnode_create() by
returning ERR_PTR(-EEXIST) instead of the node pointer when it's
already hashed and fix of avoiding the double unload_nls() on mount
failure.

Tetsuo Handa added logic of setting inode's mode as regular
file for the case of system inodes.

The rest patches fix issue of failures in generic/020,
generic/037, generic/062, generic/480, and generic/498
xfstests for the case of HFS+ file system. Currently,
only 30 xfstests' test-cases experience failures for HFS+
file system (initially, it was around 100 failed xfstests).
