instead of calling it manually in case if cifs_read_super() fails to set ->s_root, just call it from ->kill_sb(). cifs_put_super() is gone now *and* we have cifs_sb shutdown and destruction done after the superblock is gone from ->s_instances.

To close sget() races we'll need to be able to set cifs_sb up before we get the superblock, so we'll want to be able to do cifs_mount() earlier. Fortunately, it's easy to do - setting ->s_maxbytes can be done in cifs_read_super(), ditto for ->s_time_gran and as for putting MS_POSIXACL into ->s_flags, we can mirror it in ->mnt_cifs_flags until cifs_read_super() is called.

if we get to out_super with ->s_root already set (e.g. with cifs_get_root() failure), we'll end up with cifs_put_super() called and ->mountdata freed twice. We'll also get cifs_sb freed twice and cifs_sb->local_nls dropped twice. The problem is, we can get to out_super both with and without ->s_root, which makes ->put_super() a bad place for such work. Switch to ->kill_sb(), have all that work done there after kill_anon_super(). Unlike ->put_super(), ->kill_sb() is called by deactivate_locked_super() whether we have ->s_root or not.

由 Linus Torvalds 提交于
Commit 13e12d14 ("vfs: reorganize 'struct inode' layout a bit") moved things around a bit changed i_state to be unsigned int instead of unsigned long. That was to help structure layout for the 64-bit case, and shrink 'struct inode' a bit (admittedly that only happened when spinlock debugging was on and i_flags didn't pack with i_lock). However, Meelis Roos reports that this results in unaligned exceptions on sprc, and it turns out that the bit-locking primitives that we use for the I_NEW bit want to use the bitops. Which want 'unsigned long', not 'unsigned int'. We really should fix the bit locking code to not have that kind of requirement, but that's a much bigger change. So for now, revert that field back to 'unsigned long' (but keep the other re-ordering changes from the commit that caused this). Andi points out that we have played games with this in 'struct page', so it's solvable with other hacks too, but since right now the struct inode size advantage only happens with some rare config options, it's not worth fighting. It _would_ be worth fixing the bitlocking code, though. Especially since there is no type safety in the bitlocking code (this never caused any warnings, and worked fine on x86-64, because the bitlocks take a 'void *' and x86-64 doesn't care that deeply about alignment). So it's currently a very easy problem to trigger by mistake and never notice.
