Already fixed.
The following list of LTP syscalls failure noticed on qemu-arm64 with stable-rc 6.16.1-rc1 with CONFIG_ARM64_64K_PAGES=y build configuration.
Most failures report ENOSPC (28) or mkswap errors, which may be related to disk space handling in the 64K page configuration on qemu-arm64.
The issue is reproducible on multiple runs.
qemu-arm64, ltp-syscalls - 64K page size test failures list,
- fallocate04
- fallocate05
- fdatasync03
- fsync01
- fsync04
- ioctl_fiemap01
- swapoff01
- swapoff02
- swapon01
- swapon02
- swapon03
- sync01
- sync_file_range02
- syncfs01
Reproducibility:
- 64K config above listed test fails
- 4K config above listed test pass.
Regression Analysis:
- New regression? yes
Regression from 6.16? Or just from 6.15.y?
Test regression: stable-rc 6.16.1-rc1 WARNING fs jbd2 transaction.c start_this_handle
Kernel warning noticed on this stable-rc 6.16.1-rc1 this regression was reported last month on the Linux next,
Ok, no real regression here if this was already in 6.16.
Doesn't look like it got fixed in 6.17-rc1 either :(
thanks,
