* cifs: don't pass superblock to cifs_mount()Al Viro2011-06-244-22/+26
| | | | | | | | | | | | | | 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. Kill unused 'devname' argument, while we are at it... Acked-by: Pavel Shilovsky <piastryyy@gmail.com> Reviewed-by: Jeff Layton <jlayton@redhat.com> Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>

| | | | | | | | | | if cifs_sb allocation fails, we still need to drop nls we'd stashed into volume_info - the one we would've copied to cifs_sb if we could allocate the latter.

* cifs: double free on mount failureAl Viro2011-06-241-6/+8
| | | | | | | | | | | | | | | | | | 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.

* vfs: i_state needs to be 'unsigned long' for nowLinus Torvalds2011-06-201-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit 13e12d14e2dc ("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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Certain revisions of the vbios on DCE3.2 cards have a bug in the transmitter control table which prevents duallink from being enabled properly on some cards. The action switch statement jumps to the wrong offset for the OUTPUT_ENABLE action. The fix is to use the ENABLE action rather than the OUTPUT_ENABLE action on the affected cards. In fixed version of the vbios, both actions jump to the same offset, so the change should be safe.

[PATCH v2] net: rfs: enable RFS before first data packet is received First packet received on a passive tcp flow is not correctly RFS steered. One sock_rps_record_flow() call is missing in inet_accept() But before that, we also must record rxhash when child socket is setup.
