2025-07-24erofs: implement metadata compressionBo Liu (OpenAnolis)
Thanks to the meta buffer infrastructure, metadata-compressed inodes are just read from the metabox inode instead of the blockdevice (or backing file) inode. The same is true for shared extended attributes. When metadata compression is enabled, inode numbers are divided from on-disk NIDs because of non-LTS 32-bit application compatibility.

2025-07-24erofs: add on-disk definition for metadata compressionGao Xiang
Filesystem metadata has a high degree of redundancy, so it should compress well in the general case. Although metadata compression can increase overall I/O latency, many users care more about minimized image sizes than extreme runtime performance. Let's implement metadata compression in response to user requests [1]. Actually, it's quite simple to implement metadata compression: since EROFS already supports per-inode compression, we can simply treat a special inode (called `the metabox inode`) as a container for compressed inode metadata. Since EROFS supports multiple algorithms, users can even specify LZ4 for metadata and LZMA for data. To better support incremental builds, the MSB of NIDs indicates where the inode metadata is located: if bit 63 is set, the inode itself should be read from `the metabox inode`. Optionally, shared xattrs can also be kept in `the metabox inode` if COMPAT_SHARED_EA_IN_METABOX is set.

There is no need to keep additional local metabufs since we already have one in `struct erofs_map_blocks`.

In the past %pK was preferable to %p as it would not leak raw pointer values into the kernel log. Since commit ad67b74d2469 ("printk: hash addresses printed with %p") the regular %p has been improved to avoid this issue. Furthermore, restricted pointers ("%pK") were never meant to be used through printk(). They can still unintentionally leak raw pointers or acquire sleeping locks in atomic contexts.

2025-07-24serial: 8250: fix panic due to PSLVERRYunhui Cui
When the PSLVERR_RESP_EN parameter is set to 1, the device generates an error response if an attempt is made to read an empty RBR (Receive Buffer Register) while the FIFO is enabled. In serial8250_do_startup(), calling serial_port_out(port, UART_LCR, UART_LCR_WLEN8) triggers dw8250_check_lcr(), which invokes dw8250_force_idle() and serial8250_clear_and_reinit_fifos(). The latter function enables the FIFO via serial_out(p, UART_FCR, p->fcr). Execution proceeds to the serial_port_in(port, UART_RX). This satisfies the PSLVERR trigger condition. When another CPU (e.g., using printk()) is accessing the UART (UART is busy), the current CPU fails the check (value & ~UART_LCR_SPAR) == (lcr & ~UART_LCR_SPAR) in dw8250_check_lcr(), causing it to enter dw8250_force_idle(). Put serial_port_out(port, UART_LCR, UART_LCR_WLEN8) under the port->lock to fix this issue.

As this warning occurs in clang's frontend before inlining occurs, it cannot know that these conditions are indentical to avoid the warning. Manually inline cxacru_upload_firmware() into cxacru_heavy_init(), as that is its only callsite, so that clang can see that bp is initialized and used under the same condition, clearing up the warning without any functional changes to the code (LLVM was already doing this inlining later).

2025-07-24net: hns3: default enable tx bounce buffer when smmu enabledJijie Shao
The SMMU engine on HIP09 chip has a hardware issue. SMMU pagetable prefetch features may prefetch and use a invalid PTE even the PTE is valid at that time. This will cause the device trigger fake pagefaults. The solution is to avoid prefetching by adding a SYNC command when smmu mapping a iova. But the performance of nic has a sharp drop. Then we do this workaround, always enable tx bounce buffer, avoid mapping/unmapping on TX path. This issue only affects HNS3, so we always enable tx bounce buffer when smmu enabled to improve performance.
