Move prototype declaration to header file reiserfs/reiserfs.h from reiserfs/super.c because they are used by more than one file. This eliminates the following warning in reiserfs/bitmap.c: fs/reiserfs/bitmap.c:647:6: warning: no previous prototype for `show_alloc_options' [-Wmissing-prototypes] Signed-off-by:

Concurrent access to alloc_blocks in hfsplus_inode_info() is protected by extents_lock mutex. This patch fixes two instances where alloc_blocks modification was not protected with this lock. This fixes possible allocation bitmap corruption in race conditions while extending and truncating files.

Add code to check sizes of on-disk data of metadata files such as inode size, segment usage size, DAT entry size, and checkpoint size. Although these sizes are read from disk, the current implementation doesn't check them. If these sizes are not sane on disk, it can cause out-of-range access to metadata or memory access overrun on metadata block buffers due to overflow in sundry calculations. Both lower limit and upper limit of metadata sizes are verified to prevent these issues. Signed-off-by:

Add nilfs_sufile_trim_fs(), which takes an fstrim_range structure and calls blkdev_issue_discard for every clean segment in the specified range. The range is truncated to file system block boundaries. Signed-off-by:

With this ioctl the segment usage entries in the SUFILE can be updated from userspace. This is useful, because it allows the userspace GC to modify and update segment usage entries for specific segments, which enables it to avoid unnecessary write operations. If a segment needs to be cleaned, but there is no or very little reclaimable space in it, the cleaning operation basically degrades to a useless moving operation. In the end the only thing that changes is the location of the data and a timestamp in the segment usage information. With this ioctl the GC can skip the cleaning and update the segment usage entries directly instead. This is basically a shortcut to cleaning the segment. It is still necessary to read the segment summary information, but the writing of the live blocks can be skipped if it's not worth it.

Introduce nilfs_sufile_set_suinfo(), which expects an array of nilfs_suinfo_update structures and updates the segment usage information accordingly. This is basically a helper function for the newly introduced NILFS_IOCTL_SET_SUINFO ioctl. [konishi.ryusuke@lab.ntt.co.jp: use put_bh() instead of brelse() because we know bh != NULL] Signed-off-by:

The patch "rtc: verify a critical argument to rtc_update_irq() before using it" introduces validation for rtc_device in the RTC core, so there are no need to check this argument for rtc_update_irq() from the drivers. This patch removes such check for the existing rtc_update_irq() users. Signed-off-by:

NO_IRQ may be defined as '(unsigned int) -1' in some architectures (arm, sh ...), and either may not be defined in some architectures (arm64) which can enable RTC_DRV_S3C. Also since platform_get_irq returns err-code in case of any error, we do not need to intialize s3c_rtc_alarmno and s3c_rtc_tickno. Signed-off-by:

Using platform_get_irq_byname() to retrieve the IRQ number returns the VIRQ number rather than the local IRQ number for the device. Passing that value then into regmap_irq_get_virq() causes a failure because the function is expecting the local IRQ number (e.g. 0, 1, 2, 3, etc). This patch removes use of regmap_irq_get_virq() to prevent this failure from happening Signed-off-by:

Datasheet says: "When the VSRTC voltage drops to the range of 0.9 - 0.8V, the RTCPORB reset signal is generated and the contents of the RTC will be reset. <skip>. To inform the processor that the contents of the RTC are no longer valid due to the reset, a timer reset interrupt function is implemented with the RTCRSTI bit." This patch makes the RTC valid by default until RTCRST interrupt occurs. Signed-off-by:
