Change the list operation to only return whether or not an attribute
should be listed. Copying the attribute names into the buffer is moved
to the callers.Since the result only depends on the dentry and not on the attribute
name, we do not pass the attribute name to list operations.Signed-off-by: Andreas Gruenbacher

new method: ->get_link(); replacement of ->follow_link(). The differences
are:
* inode and dentry are passed separately
* might be called both in RCU and non-RCU mode;
the former is indicated by passing it a NULL dentry.
* when called that way it isn't allowed to block
and should return ERR_PTR(-ECHILD) if it needs to be called
in non-RCU mode.It's a flagday change - the old method is gone, all in-tree instances
converted. Conversion isn't hard; said that, so far very few instances
do not immediately bail out when called in RCU mode. That'll change
in the next commits.Signed-off-by: Al Viro

Add an additional "name" field to struct xattr_handler. When the name
is set, the handler matches attributes with exactly that name. When the
prefix is set instead, the handler matches attributes with the given
prefix and with a non-empty suffix.This patch should avoid bugs like the one fixed in commit c361016a in
the future.Signed-off-by: Andreas Gruenbacher

The xattr_handler operations are currently all passed a file system
specific flags value which the operations can use to disambiguate between
different handlers; some file systems use that to distinguish the xattr
namespace, for example. In some oprations, it would be useful to also have
access to the handler prefix. To allow that, pass a pointer to the handler
to operations instead of the flags value alone.Signed-off-by: Andreas Gruenbacher

1. Rename dequeue_signal_lock() to kernel_dequeue_signal(). This
matches another "for kthreads only" kernel_sigaction() helper.2. Remove the "tsk" and "mask" arguments, they are always current
and current->blocked. And it is simply wrong if tsk != current.3. We could also remove the 3rd "siginfo_t *info" arg but it looks
potentially useful. However we can simplify the callers if we
change kernel_dequeue_signal() to accept info => NULL.4. Remove _irqsave, it is never called from atomic context.

Li Zefan reported an unbalanced locking issue, found by his
internal debugging feature on runtime. The particular case he was
looking at doesn't lead to a deadlock, as the structure that this lock
is embedded in is freed on error. But we should straighten out the error
handling.Because several callers of jffs2_do_read_inode_internal() /
jffs2_do_read_inode() already handle the locking/unlocking and inode
clearing at their own level, let's just push any unlocks/clearing down
to the caller. This consistency is much easier to verify.Reported-by: Li Zefan

Pull MTD updates from Brian Norris:
"Common MTD:- Add Kconfig option for keeping both the 'master' and 'partition'
MTDs registered as devices. This would really make a better
default if we could do it over, as it allows a lot more flexibility
in (1) determining the flash topology of the system from user-space
and (2) adding temporary partitions at runtime (ioctl(BLKPG)).Unfortunately, this would possibly cause user-space breakage, as it
will cause renumbering of the /dev/mtdX devices. We'll see if we
can change this in the future, as there have already been a few
people looking for this feature, and I know others have just been
working around our current limitations instead of fixing them this
way.- Along with the previous change, add some additional information to
sysfs, so user-space can read the offset of each partition within
its master deviceSPI NOR:
- add new device tree compatible binding to represent the
mostly-compatible class of SPI NOR flash which can be detected by
their extended JEDEC ID bytes, cutting down the duplication of our

Convert the following where appropriate:
(1) S_ISLNK(dentry->d_inode) to d_is_symlink(dentry).
(2) S_ISREG(dentry->d_inode) to d_is_reg(dentry).
(3) S_ISDIR(dentry->d_inode) to d_is_dir(dentry). This is actually more
complicated than it appears as some calls should be converted to
d_can_lookup() instead. The difference is whether the directory in
question is a real dir with a ->lookup op or whether it's a fake dir with
a ->d_automount op.In some circumstances, we can subsume checks for dentry->d_inode not being
NULL into this, provided we the code isn't in a filesystem that expects
d_inode to be NULL if the dirent really *is* negative (ie. if we're going to
use d_inode() rather than d_backing_inode() to get the inode pointer).Note that the dentry type field may be set to something other than
DCACHE_MISS_TYPE when d_inode is NULL in the case of unionmount, where the VFS
manages the fall-through from a negative dentry to a lower layer. In such a
case, the dentry type of the negative union dentry is set to the same as the
type of the lower dentry.However, if you know d_inode is not NULL at the call site, then you can use
the d_is_xxx() functions even in a filesystem.There is one further complication: a 0,0 chardev dentry may be labelled
DCACHE_WHITEOUT_TYPE rather than DCACHE_SPECIAL_TYPE. Strictly, this was
intended for special directory entry types that don't have attached inodes.The following perl+coccinelle script was used:
use strict;
my @callers;
open($fd, 'git grep -l \'S_IS[A-Z].*->d_inode\' |') ||

Remove the function pulledbits() that is not used anywhere.
This was partially found by using a static code analysis program called cppcheck.

schedule_delayed_work() happening when the work is already pending is
a cheap no-op. Don't bother with ->wbuf_queued logics - it's both
broken (cancelling ->wbuf_dwork leaves it set, as spotted by Jeff Harris)
and pointless. It's cheaper to let schedule_delayed_work() handle that
case.Reported-by: Jeff Harris

Now with 64bit bzImage and kexec tools, we support ramdisk that size is
bigger than 2g, as we could put it above 4G.Found compressed initramfs image could not be decompressed properly. It
turns out that image length is int during decompress detection, and it
will become < 0 when length is more than 2G. Furthermore, during
decompressing len as int is used for inbuf count, that has problem too.Change len to long, that should be ok as on 32 bit platform long is
32bits.Tested with following compressed initramfs image as root with kexec.
gzip, bzip2, xz, lzma, lzop, lz4.
