Subject: inboxwritable: delay umask_prepare calls
X-Git-Tag: v1.7.0~1502
X-Git-Url: http://www.git.stargrave.org/?p=public-inbox.git;a=commitdiff_plain;h=b3cf37096874c6c80ef554e5153e5d995c72ab95

inboxwritable: delay umask_prepare calls

This simplifies all ->with_umask callers and opens the
door for further optimizations to delay/elide process spawning.
