Subject: the second vfs pile - rebase or no rebase?
The thing is, there's a couple of trivial conflicts on merge.
One in drivers/staging/gdm72xx/usb_boot.c (my patch has set_fs()
removed, since it's immediately followed by goto restore_fs, where
we do the same set_fs() anyway, and in your tree ret = -ENOENT; right
before that line is replaced with more informative ret = PTR_ERR(filp);
the conflict is resolved by keeping the assignment from your tree
and removing set_fs() call). Another is in drivers/usb/gadget/storage_common.c,
where you have
if (fsg_lun_is_open(curlun))
fsg_lun_close(curlun);
curlun->blksize = blksize;
curlun->blkbits = blkbits;
added around the get_file(filp) line that had been removed in my branch.
Resolved by keeping these added lines and dropping get_file() one...
Alternatively, I can rebase the damn thing; up to you. I would've
done just that (there's very little chance of this stuff having been pulled
anywhere in the few days this part of queue had been public), but considering
the fuckup in the first pile when I hadn't noticed the trouble to nfs.git
caused by rebase...
The stuff in there: fsfreeze deadlock fixes by Jan (essentially,
the deadlock reproduced by xfstests 068), symlink and hardlink
restriction patches (I still think that this is pointless as all
"security sclerosis^Whardening" tends to be, but Kees has addressed the
rest of objections and result is reasonably sane), plus assorted cleanups
and fixes. Note that another fsfreeze deadlock (emergency thaw one) is *not*
dealt with - the series by Fernando conflicts a lot with Jan's, breaks
userland ABI (FIFREEZE semantics gets changed) and trades the deadlock
for massive vfsmount leak; this is going to be handled next cycle. There
probably will be another pull request, but that stuff won't be in it.
Sorry.
In case you prefer to pull it as-is and resolve the conflicts
in merge commit, it's in the usual place -

Shortlog:
Al Viro (24):
move spu_forget() into spufs_rmdir()

spufs: pull unlock-and-dput() up into spufs_create()
pull unlock+dput() out into do_spu_create()
new helper: done_path_create()
mknod: take sanity checks on mode into the very beginning
pull mnt_want_write()/mnt_drop_write() into kern_path_create()/done_path_create() resp.
clean unix_bind() up a bit
sanitize ecryptfs_lookup()
ecryptfs_lookup_interpose(): allocate dentry_info first
uninline file_free_rcu()
take grabbing f->f_path to do_dentry_open()

switch the protection of percpu_counter list to spinlock
delousing target_core_file a bit
