[LU-14047] change EWOULDBLOCK to EAGAIN, add EWOULDBLOCK to spelling.txt

Fri, 26 Feb 2021 21:17:31 +0000

It's possible to find places in the clio stack where rc is set to -EWOULDBLOCK and later compared to -EAGAIN. And if we're looking at the logs and wonder where rc=-11 came from then we much search for both constants. This is confusing and makes analysis harder than it should be.

We should change all EWOULDBLOCK instances to EAGAIN and add EWOULDBLOCK||EAGAIN to spelling.txt.

fs/lustre-release$ git grep EAGAIN | wc -l
     272
fs/lustre-release$ git grep EWOULDBLOCK | wc -l
      35
