There are a number of fixes as well. The entire changeset is pretty big, but most of it is code movement. Several of these commits are quite new; the history got very messed up due to a mismerge with the urgent changes for rc8 which completely broke IA64, and so Ingo requested that we rebase it to straighten it out." * 'x86-efi-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: efi: remove "kfree(NULL)" efi: locking fix in efivar_entry_set_safe() efi, pstore: Read data from variable store before memcpy() efi, pstore: Remove entry from list when erasing efi, pstore: Initialise 'entry' before iterating efi: split efisubsystem from efivars efivarfs: Move to fs/efivarfs efivars: Move pstore code into the new EFI directory efivars: efivar_entry API efivars: Keep a private global pointer to efivars efi: move utf16 string functions to efi.h x86, efi: Make efi_memblock_x86_reserve_range more readable efivarfs: convert to use simple_open()

This move will eventually allow us to enable the efivarfs code without having to also enable CONFIG_EFI_VARS built, and vice versa. Furthermore, things like, mount -t efivarfs none /sys/firmware/efi/efivars will now work if efivarfs is built as a module without requiring the use of MODULE_ALIAS(), which would have been necessary when the efivarfs code was part of efivars.c.

The be2net driver had a bug fix in 'net' that overlapped with the VLAN interface changes by Patrick McHardy in net-next. An IGB conflict existed because in 'net' the build_skb() support was reverted, and in 'net-next' there was a comment style fix within that code. Several batman-adv conflicts were resolved by making sure that all calls to batadv_is_my_mac() are changed to have a new bat_priv first argument. Eric Dumazet's TS ECR fix in TCP in 'net' conflicted with the F-RTO rewrite in 'net-next', mostly overlapping changes.

To not break compatibility, some fragments from lksctp-tools' netinet/sctp.h have been carefully included, while taking care that neither kernel nor user land breaks, so both compile fine with this change (for lksctp-tools I tested with the old netinet/sctp.h header and with a newly adapted one that includes the uapi sctp header). lksctp-tools smoke test run through successfully as well in both cases.

This means we can end up fetching the wrong blocks for readahead for file systems > 16TB. Linus found this when experimenting with an enhacement to the sparse static code checker which checks for missing widening casts before binary "not" operators.

And a getdents will fail if the user only want to get '.' and what's worse, if there is a conversion happens when the user calls getdents many times, he/she may get the same entry twice. In theory, a dir block would also fail if it is converted to a hashed-index based dir since f_pos will become a hash value, not the real one, but it doesn't happen. And a deep investigation shows that we uses a hash based solution even for a normal dir if the dir_index feature is enabled. So this patch just adds a new htree_inlinedir_to_tree for inline dir, and if we find that the hash index is supported, we will do like what we do for a dir block.

This is mostly due to credits required for allocation of quota structures (credits there are heavily overestimated but it's difficult to make better estimates if we don't want to wire non-trivial assumptions about quota format into filesystem). So move quota initialization out of allocation transaction. That way transaction for quota structure allocation will be started only if we need to look up quota structure on disk (rare) and furthermore it will be started for each quota type separately, not for all of them at once. This reduces maximum transaction size to 34 is most cases and to 73 in the worst case. [ Modified by tytso to clean up the cleanup paths for error handling. Also use a separate call to ext4_std_error() for each failure so it is easier for someone who is debugging a problem in this function to determine which function call failed. ] Signed-off-by: Jan Kara <jack@suse.cz> Signed-off-by: "Theodore Ts'o" <tytso@mit.edu>

This makes that structure pretty heavy (1 KB for pointers + 16 bytes per page attached to the bio). Also later we would like to share ext4_io_end structure among several bios in case IO to a single extent needs to be split among several bios and pointing to pages from ext4_io_end makes this complex. We remove page pointers from ext4_io_end and use pointers from bio itself instead. This isn't as easy when blocksize < pagesize because then we can have several bios in flight for a single page and we have to be careful when to call end_page_writeback(). However this is a known problem already solved by block_write_full_page() / end_buffer_async_write() so we mimic its behavior here. We mark buffers going to disk with BH_Async_Write flag and in ext4_bio_end_io() we check whether there are any buffers with BH_Async_Write flag left. If there are not, we can call end_page_writeback().
