[PATCH 1/2] mtd: nand: introduce NAND_ROW_ADDR_3 flag

Several drivers check ->chipsize to see if the third row address cycle is needed. Instead of embedding magic sizes such as 32MB, 128MB in drivers, introduce a new flag NAND_ROW_ADDR_3 for clean-up. Since nand_scan_ident() knows well about the device, it can handle this properly. The flag is set

[PATCH 0/2] mtd: nand: introduce NAND_ROW_ADDR_3 flag and improve Denali driver

Currently, Denali NAND driver always expects 3 row address cycle devices because the driver init code hard-code the register setting. I will fix it in 2/2. Many drivers check chip->chipsize if the third row address cycle is needed or not. This is not nice because 32MB, 128MB are magic numbers.

[PATCH v2 0/5] ext4: DAX data corruption fixes

[PATCH v2 1/5] ext4: prevent data corruption with inline data + DAX

If an inode has inline data it is currently prevented from using DAX by a check in ext4_set_inode_flags(). When the inode grows inline data via ext4_create_inline_data() or removes its inline data via ext4_destroy_inline_data_nolock(), the value of S_DAX can change. Currently these changes are

[PATCH v2 3/5] ext4: add sanity check for encryption + DAX

We prevent DAX from being used on inodes which are using ext4's built in encryption via a check in ext4_set_inode_flags(). We do have what appears to be an unsafe transition of S_DAX in ext4_set_context(), though, where S_DAX can get disabled without us doing a proper writeback + invalidate.

[PATCH v2 2/5] ext4: prevent data corruption with journaling + DAX

The current code has the potential for data corruption when changing an inode's journaling mode, as that can result in a subsequent unsafe change in S_DAX. I've captured an instance of this data corruption in the following fstest: https://patchwork.kernel.org/patch/9948377/ Prevent this data

[PATCH 3/3] ext4: test for inline data + DAX corruption

Add a regression test for the following kernel commit: ext4: prevent data corruption with inline data + DAX The test passes either if we don't encounter corruption, or if mounting with DAX + inline data fails. The latter is the way that we prevent this issue in the kernel. Signed-off-by:

RE: Extended IDR API

This improvement is good. But I have a concern that the parameters of idr_alloc and idr_alloc_ul are different. I mean in idr_alloc, we have start and end. In our new API, we keep them. So our design goal is to make them consistent. Your new API has its advantage surely. If you want to change

[PATCH 3/4] nvmem: remove inline in drivers/nvmem/core.c

[PATCH v4] tpm_tis_spi: Use DMA-safe memory for SPI transfers

The buffers used as tx_buf/rx_buf in a SPI transfer need to be DMA-safe. This cannot be guaranteed for the buffers passed to tpm_tis_spi_read_bytes and tpm_tis_spi_write_bytes. Therefore, we need to use our own DMA-safe buffer and copy the data to/from it. The buffer needs to be allocated
