I am running into this compile error with Linux kernel 5.15.171 in OpenWrt on 32 bit systems.
```
fs/udf/namei.c: In function 'udf_rename':
fs/udf/namei.c:878:1: error: the frame size of 1144 bytes is larger than 1024 bytes [-Werror=frame-larger-than=]
878 | }

cc1: all warnings being treated as errors
make[2]: *** [scripts/Makefile.build:289: fs/udf/namei.o] Error 1
make[1]: *** [scripts/Makefile.build:552: fs/udf] Error 2
```
This problem was introduced with kernel 5.15.169.
The first patch needs an extra linux/slab.h include on x86, which is the only modification I did to it compared to the upstream version.
These patches should go into 5.15. They were already backported to kernel 6.1.

udf: Allocate name buffer in directory iterator on heap
udf: Avoid directory type conversion failure due to ENOMEM
