Subject: [PATCH] cifs: return the more nuanced writeback error on close()
Git-commit: 2b058acecf56f6b8fac781911a683219b9ca3b7b
References: bsc#1190317
Patch-mainline: v5.18
As filemap_check_errors() only report -EIO or -ENOSPC, we return more nuanced
writeback error -(file->f_mapping->wb_err & MAX_ERRNO).
filemap_write_and_wait
filemap_write_and_wait_range
filemap_check_errors
-ENOSPC or -EIO
filemap_check_wb_err
errseq_check
return -(file->f_mapping->wb_err & MAX_ERRNO)
