jbd: Provide function to check whether transaction will issue data barrier

Provide a function which returns whether a transaction with given tid
will send a barrier to the filesystem device. The function will be used
by ext3 to detect whether fsync needs to send a separate barrier or not.

9 years agoBKL: Remove BKL from ext2 filesystem
Jan Blunck [Wed, 14 Apr 2010 12:38:39 +0000]
BKL: Remove BKL from ext2 filesystem

The BKL is still used in ext2_put_super(), ext2_fill_super(), ext2_sync_fs()
ext2_remount() and ext2_write_inode(). From these calls ext2_put_super(),
ext2_fill_super() and ext2_remount() are protected against each other by
the struct super_block s_umount rw semaphore. The call in ext2_write_inode()
could only protect the modification of the ext2_sb_info through
ext2_update_dynamic_rev() against concurrent ext2_sync_fs() or ext2_remount().
ext2_fill_super() and ext2_put_super() can be left out because you need a
valid filesystem reference in all three cases, which you do not have when
you are one of these functions.

If the BKL is only protecting the modification of the ext2_sb_info it can
safely be removed since this is protected by the struct ext2_sb_info s_lock.

Add a spinlock that protects against concurrent modifications of

superblock's buffer pointed to by sbi->s_es. The spinlock is now used in
ext2_xattr_update_super_block() which was setting the
EXT2_FEATURE_COMPAT_EXT_ATTR flag on the superblock without protection
before. Likewise the spinlock is used in ext2_show_options() to have a
consistent view of the mount options.

ext2: Remove duplicate code from ext2_sync_fs()

Depending in the state (valid or unchecked) of the filesystem either
ext2_sync_super() or ext2_commit_super() is called. If the filesystem is
currently valid (it is checked), we first mark it unchecked and afterwards
duplicate the work that ext2_sync_super() is doing later. Therefore this
patch removes the duplicate code and calls ext2_sync_super() directly after
marking the filesystem unchecked.

Alan Stern [Wed, 12 May 2010 22:21:35 +0000]
USB: EHCI: fix controller wakeup flag settings during suspend

This patch (as1380) fixes a bug in the wakeup settings for EHCI host
controllers.  When the controller is suspended, if it isn't enabled
for remote wakeup then we have to turn off all the port wakeup flags.
Disabling PCI PME# isn't good enough, because some systems (Intel)
evidently use alternate wakeup signalling paths.

In addition, the patch improves the handling of the Intel Moorestown
hardware by performing various power-up and power-down delays just
once instead of once for each port (i.e., the delays are moved outside
of the port loops).  This requires extra code, but the total delay
time is reduced.

There are also a few additional minor cleanups.

Anand Gadiyar [Thu, 6 May 2010 14:39:48 +0000]
USB: ehci-omap: Fix resume failures after bus suspend

An undocumented "feature" in the OMAP3 EHCI controller causes
suspended ports to be taken out of suspend when the USBCMD.Run/Stop
bit is cleared (this bit is normally cleared when ehci_bus_suspend
is called).

This "feature" breaks suspend-resume if the root-hub is allowed
to suspend. (The controller thinks it is in resume, and the PHY
thinks it is still in suspend).

There is an undocumented register bit that can be used to disable
this feature and restore normal behavior. Set this bit so
suspend-resume can work normally.

Tested on OMAP3 SDPs with the NXP ISP1504 and NXP ISP1703 PHYs.

that when a driver is unbound or binding fails, runtime PM for the
