This creates a new fsmonitor-ll.h with most of the functions from fsmonitor.h, though it leaves three inline functions where they were. Two-thirds of the files that previously included fsmonitor.h did not need those three inline functions or the six extra includes those inline functions required, so this allows them to only include the lower level header.

/*
|
|
* For the builtin FSMonitor, we create the Unix domain socket for the
|
|
* IPC in the .git directory. If the working directory is remote,
|
|
* then the socket will be created on the remote file system. This
|
|
* can fail if the remote file system does not support UDS file types
|
|
* (e.g. smbfs to a Windows server) or if the remote kernel does not
|
|
* allow a non-local process to bind() the socket. (These problems
|
|
* could be fixed by moving the UDS out of the .git directory and to a
|
|
* well-known local directory on the client machine, but care should
|
|
* be taken to ensure that $HOME is actually local and not a managed
|
|
* file share.)
|
|
*
|
|
* FAT32 and NTFS working directories are problematic too.
|
|
*
|
|
* The builtin FSMonitor uses a Unix domain socket in the .git
|
|
* directory for IPC. These Windows drive formats do not support
|
|
* Unix domain sockets, so mark them as incompatible for the daemon.
