Pass the larger struct fs_disk_quota to the ->set_dqblk operation so
that the Q_SETQUOTA and Q_XSETQUOTA operations can be implemented
with a single filesystem operation and we can retire the ->set_xquota
operation.  The additional information (RT-subvolume accounting and
warn counts) are left zero for the VFS quota implementation.

Add new fieldmask values for setting the numer of blocks and inodes
values which is required for the VFS quota, but wasn't for XFS.

ext3: make barrier options consistent with ext4 · 0636c73e

Eric Sandeen authored Apr 30, 2010

ext4 was updated to accept barrier/nobarrier mount options
in addition to the older barrier=0/1.  The barrier story
is complex enough, we should help people by making the options
the same at least, even if the defaults are different.

This patch allows the barrier/nobarrier mount options for ext3,
while keeping nobarrier the default.

It also unconditionally displays barrier status in show_options,
and prints a message at mount time if barriers are not enabled,
just as ext4 does.

quota: Make quota stat accounting lockless. · dde95888

Dmitry Monakhov authored Apr 26, 2010

Quota stats is mostly writable data structure. Let's alloc percpu
bucket for each value.

NOTE: dqstats_read() function is racy against dqstats_{inc,dec}
and may return inconsistent value. But this is ok since absolute
accuracy is not required.

ext3: Fix waiting on transaction during fsync · 52779708

Jan Kara authored Apr 15, 2010

log_start_commit() returns 1 only when it started a transaction
commit. Thus in case transaction commit is already running, we
fail to wait for the commit to finish. Fix the issue by always
waiting for the commit regardless of the log_start_commit return
value.

jbd: Provide function to check whether transaction will issue data barrier · 03f4d804

Jan Kara authored Apr 15, 2010

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.
