[PATCH v3 0/4] block: improve error reporting for unsupported O_DIRECT
Posted by Daniel P. Berrangé 5 years, 3 months ago
v1: https://lists.gnu.org/archive/html/qemu-devel/2020-07/msg00269.html
v2: https://lists.gnu.org/archive/html/qemu-devel/2020-07/msg00589.html

See patch commit messages for rationale

Ideally we would convert other callers of qemu_open to use
qemu_open_err, and eventually remove qemu_open, renaming
qemu_open_err back to qemu_open.  Given soft freeze is just
days away though, I'm hoping this series is simple enough
to get into this release, leaving bigger cleanup for later.

Improved in v3:

 - Re-arrange the patches series, so that the conversion to Error
   takes place first, then the improve O_DIRECT reporting
 - Rename existing method to qemu_open_old
 - Use a pair of new methods qemu_open + qemu_create to improve
   arg checking

Improved in v2:

 - Mention that qemu_open_err is preferred over qemu_open
 - Get rid of obsolete error_report call
 - Simplify O_DIRECT handling
 - Fixup iotests for changed error message text

Daniel P. Berrangé (4):
  util: rename qemu_open() to qemu_open_old()
  util: introduce qemu_open and qemu_create with error reporting
  util: give a specific error message when O_DIRECT doesn't work
  block: switch to use qemu_open/qemu_create for improved errors
