2.30.0

30d13b7

mergerfs-2.30.0

If you find mergerfs and/or my other work useful please consider supporting their development.

Features

inodecalc: new argument that allows controlling how inodes are calculated. Can help with NFS stale file handle errors.
nfsopenhack: new argument that helps working around issues with certain issues with NFS not being fully POSIX compatible when exporting mergerfs.
new msp policies: "most shared path". Like ep path preserving policies but will walk back the directory tree till something is found.
readdirplus: when a readdir happens mergerfs can stat files at the same time. Similar to the NFS feature. Might improve directory listing performance depending on use case.
config file: Allows you to put config arguments in a "ini" like file (key=val) and reference that in the mount options.
new runtime API based on ioctl (will be removing the xattr based API in mergerfs 3.0)
moveonenospc: now uses policies just like the regular filesystem functions providing more control over where the file goes.

Bug fixes

Fix building on FreeBSD
Reworked readdir code in general and fixed a NFS readdir race condition that is in libfuse
inodecalc algo that makes mergerfs work better with some 32bit software that doesn't handle 64bit inode values
inodecalc algo that helps with changing files out of band problems when exporting mergerfs through NFS.
fixed deb package building that broken mounting as non-root

misc

misc updates to docs
general code cleanup
prep for mergerfs v3.0 (which will be a breaking change with regard to options)
