Hmmm. There are still people who have their editor setup with tabwidth 4. Some of the entries were added with tabwidth 4, and for these people the lineup looks OK. But in the Linux kernel source we use tabwidth 8. This patch repairs that whitespace so that the number align properly. Signed-off-by:

As our device may be hot-unplugged and framebuffer cannot handle this case by itself we need to keep track of usage count so as to release fb_info and framebuffer memory only after the last user has closed framebuffer. We need to do the freeing in a scheduled work as fb_release() is called with fb_info lock held. Signed-off-by:

Reallocating memory in depth change does not work well if some userspace application has mmapped() the framebuffer as that mapping does not get adjusted (thus application continues to write to old buffer). In addition doing deferred_io_cleanup() and init() inside of set_par() tends to deadlock with fbcon's flashing cursor. Avoid all this by allocating a buffer that can hold 8bpp framebuffer and just use 1/8 of it while running at 1bpp. Signed-off-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:

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().
