Subject: [GIT PULL] erofs fix for 6.19-rc3

Hi Linus,

Could you consider this fix for 6.19-rc3?

Junbeom reported that synchronous reads could hit unintended EIOs
under memory pressure due to incorrect error propagation in
z_erofs_decompress_queue(), where earlier physical clusters in
the same decompression queue may be served for another readahead.

This patch addresses the issue by decompressing each physical cluster
independently as long as disk I/Os succeed, rather than being impacted
by the error status of previous physical clusters in the same queue.

Happy Xmas and new year in advance!

Thanks,
Gao Xiang
