# When adding a new wait event, make sure it is placed in the appropriate

# ClassName section.

#

# Wait events added in stable branches should be appended to the lists in

# the "ABI_compatibility:" region of their related ClassName section to

# preserve ABI compatibility of the C code generated from this file's data,

# respecting the order of any wait event already listed there. The

# "ABI_compatibility:" regions should remain empty on the master branch and

# on unreleased branches.

#

# WaitEventLWLock and WaitEventLock have their own C code for their wait event

# enums and function names. Hence, for these, only the SGML documentation is

# generated.
