[PATCH v2 1/4] Revert "util: virlog: Introduce wildcard to log filters"

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



This reverts commit 8daa593b0741452a78daea76075254ae7d3c6ab6.

There are two undesirable aspects to the impl

  - Only a bare wildcard is permitted
  - The wildcard match is not performed in the order listed
