As a follow-up to the thread about RTC support for some Loongson 2E/2F boards, this patch tries to address the "REVISIT"/"FIXME" comments about rtc binary mode handling and allow rtc to work with rtc in binary mode. I've also raised the message about 24-h mode not supported to warning otherwise, one may end up with no rtc without any message in the kernel log. Signed-off-by:

The "nofpu" and "nodsp" kernel command line options currently do not affect CPUs that are brought online later in the boot process or hotplugged at runtime. It is desirable to apply the nofpu/nodsp options to all CPUs in the system, so that surprising results are not seen when a process migrates from one CPU to another. [Ralf: Moved definitions of mips_fpu_disabled, fpu_disable, mips_dsp_disabled and dsp_disable from setup.c to cpu-probe.c to allow making mips_fpu_disabled and mips_dsp_disabled static.] Signed-off-by:

Modifications to the boot memory allocation structures to make them easier to read and maintain.

dquot_transfer() acquires own references to dquots via dqget(). Thus it waits for dq_lock which creates a lock inversion because dq_lock ranks above transaction start but transaction is already started in ocfs2_setattr(). Fix the problem by passing own references directly to __dquot_transfer. Acked-by:

commit_dqblk() can write quota info to global file. That is actually a bad thing to do because if we are just modifying local quota file, we are not prepared (do not hold proper locks, do not have transaction credits) to do a modification of the global quota file. So do not use commit_dqblk() and instead call our writing function directly. Acked-by:

OCFS2 had three issues with quota locking: a) When reading dquot from global quota file, we started a transaction while holding dqio_mutex which is prone to deadlocks because other paths do it the other way around b) During ocfs2_sync_dquot we were not protected against concurrent writers on the same node. Because we first copy data to local buffer, a race could happen resulting in old data being written to global quota file and thus causing quota inconsistency after a crash. c) ip_alloc_sem of quota files was acquired while a transaction is started in ocfs2_quota_write which can deadlock because we first get ip_alloc_sem and then start a transaction when extending quota files. We fix the problem a) by pulling all necessary code to ocfs2_acquire_dquot and ocfs2_release_dquot. Thus we no longer depend on generic dquot_acquire to do the locking and can force proper lock ordering. Problems b) and c) are fixed by locking i_mutex and ip_alloc_sem of global quota file in ocfs2_lock_global_qf and removing ip_alloc_sem from ocfs2_quota_read and ocfs2_quota_write. Acked-by:

The position of global quota file info does not change. So we do not have to do logical -> physical block translation every time we reread it from disk. Thus we can also avoid taking ip_alloc_sem. Acked-by:

Jan Kara authored
There is no need to map offset of local dquot structure to on disk block in each quota write. It is enough to map it just once and store the physical block number in quota structure in memory. Moreover this simplifies locking as we do not have to take ip_alloc_sem from quota write path. Acked-by:

Currently, __dquot_transfer() acquires its own references of dquot structures that will be put into inode. But for OCFS2, this creates a lock inversion between dq_lock (waited on in dqget) and transaction start (started in ocfs2_setattr). Currently, deadlock is impossible because dq_lock is acquired only during dquot_acquire and dquot_release and we already hold a reference to dquot structures in ocfs2_setattr so neither of these functions can be called while we call dquot_transfer. But this is rather subtle and it is hard to teach lockdep about it. So provide __dquot_transfer function that can be passed dquot references directly. OCFS2 can then pass acquired dquot references directly to __dquot_transfer with proper locking. Signed-off-by: -

Quota must being initialized if size or uid/git changes requested. But initialization performed in two different places: in case of i_size file system is responsible for dquot init , but in case of uid/gid init will be called internally in dquot_transfer(). This ambiguity makes code harder to understand. Let's move this logic to one common helper function. Signed-off-by:

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. Signed-off-by:
