Both of commits f94116ae ("ide: cleanup <asm-m68k/ide.h>") and 15a453a9 ("ide: include <asm/ide.h> only when needed") break falconide: | Uniform Multi-Platform E-IDE driver | ide: Falcon IDE controller | Probing IDE interface ide0... | hda: Sarge m68k, ATA DISK drive | ide0 at 0xfff00000 on irq 15 (serialized) | ide-gd driver 1.18 | hda: max request size: 128KiB | hda: 2118816 sectors (1084 MB) w/256KiB Cache, CHS=2102/16/63 | hda:<4>hda: lost interrupt This happens because falconide relies on {in,out}sw() being redefined in <asm/ide.h>, as included by <linux/ide.h>, which is no longer the case. Use __ide_mm_{in,out}sw() from <asm/ide.h> instead, just like ide_{in,out}put_data() do. The same problem seems to exist in q40ide. Signed-off-by:

commit 255115fb ("ide: allow host drivers to specify IRQ flags") added irq_flags fields to struct ide_port_info and struct ide_host. Drivers can now set ide_port_info.irq_flags = IRQF_SHARED, while init_irq() passes ide_host.irq_flags to request_irq(). Unfortunately ide_host.irq_flags is never set, causing (on ARAnyM): | Uniform Multi-Platform E-IDE driver | ide: Falcon IDE controller | Probing IDE interface ide0... | hda: Sarge m68k, ATA DISK drive | init_irq: sa = 0 | ide0: disabled, unable to get IRQ 15 | ide0: failed to initialize IDE interface | ide0: disabling port Solve this by copying ide_port_info.irq_flags to ide_host.irq_flags in ide_host_alloc(). This bug probably affects the following IDE host drivers: - buddha - delkin_cb - falconide - gayle - ide-cs - macide - q40ide - scc_pata - sgiioc4 Signed-off-by:

The code that enables branch tracing for all (non-constant) branches plays games with the preprocessor and #define's the C 'if ()' construct to do tracing. That's all fine, but it fails for some unusual but valid C code that is sometimes used in macros, notably by the intel-iommu code: if (i=drhd->iommu, drhd->ignored) .. because now the preprocessor complains about multiple arguments to the 'if' macro. So make the macro expansion of this particularly horrid trick use varargs, and handle the case of comma-expressions in if-statements. Use another macro to do it cleanly in just one place. This replaces a patch by David (and acked by Steven) that did this all inside that one already-too-horrid macro. Tested-by:

There's a possible deadlock in generic_file_splice_write(), splice_from_pipe() and ocfs2_file_splice_write(): - task A calls generic_file_splice_write() - this calls inode_double_lock(), which locks i_mutex on both pipe->inode and target inode - ordering depends on inode pointers, can happen that pipe->inode is locked first - __splice_from_pipe() needs more data, calls pipe_wait() - this releases lock on pipe->inode, goes to interruptible sleep - task B calls generic_file_splice_write(), similarly to the first - this locks pipe->inode, then tries to lock inode, but that is already held by task A - task A is interrupted, it tries to lock pipe->inode, but fails, as it is already held by task B - ABBA deadlock Fix this by explicitly ordering locks: the outer lock must be on target inode and the inner lock (which is later unlocked and relocked) must be on pipe->inode. This is OK, pipe inodes and target inodes form two nonoverlapping sets, generic_file_splice_write() and friends are not called with a target which is a pipe. Signed-off-by:

After a review of user's feedback for finding out other compatibility issues, I found nilfs improperly initializes timestamps in inode; CURRENT_TIME was used there instead of CURRENT_TIME_SEC even though nilfs didn't have nanosecond timestamps on disk. A few users gave us the report that the tar program sometimes failed to expand symbolic links on nilfs, and it turned out to be the cause. Instead of applying the above displacement, I've decided to support nanosecond timestamps on this occation. Fortunetaly, a needless 64-bit field was in the nilfs_inode struct, and I found it's available for this purpose without impact for the users. So, this will do the enhancement and resolve the tar problem. Signed-off-by:

The former versions didn't have extra super blocks. This improves the weak point by introducing another super block at unused region in tail of the partition. This doesn't break disk format compatibility; older versions just ingore the secondary super block, and new versions just recover it if it doesn't exist. The partition created by an old mkfs may not have unused region, but in that case, the secondary super block will not be added. This doesn't make more redundant copies of the super block; it is a future work. Signed-off-by:

will reduce some lines of segment constructor. Previously, the state was complexly controlled through a list of segments in order to keep consistency in meta data of usage state of segments. Instead, this presents ``calculated'' active flags to userland cleaner program and stop maintaining its real flag on disk. Only by this fake flag, the cleaner cannot exactly know if each segment is reclaimable or not. However, the recent extension of nilfs_sustat ioctl struct (nilfs2-extend-nilfs_sustat-ioctl-struct.patch) can prevent the cleaner from reclaiming in-use segment wrongly. So, now I can apply this for simplification. Signed-off-by:

Nilfs creates checkpoints even for garbage collection or metadata updates such as checkpoint mode change. So, user often sees checkpoints created only by such internal operations. This is inconvenient in some situations. For example, application that monitors checkpoints and changes them to snapshots, will fall into an infinite loop because it cannot distinguish internally created checkpoints. This patch solves this sort of problem by adding a flag to checkpoint for identification. Signed-off-by:

The sketch file is a file to mark checkpoints with user data. It was experimentally introduced in the original implementation, and now obsolete. The file was handled differently with regular files; the file size got truncated when a checkpoint was created. This stops the special treatment and will treat it as a regular file. Most users are not affected because mkfs.nilfs2 no longer makes this file. Signed-off-by:
