Subject: [PATCH] shm: Close file descriptors not needed
|
||||
|
||||
Commit 5a981ee8 implemented a fallback path for platforms which do not
|
||||
support mremap() such as FreeBSD.
|
||||
|
||||
To do so, the file descriptor for the mmap() is not closed immediately
|
||||
but instead kept as long as the pool exists.
|
||||
|
||||
That induces more file descriptors kept open for longer, which in turn
|
||||
may cause problems as wl_shm may be using a lot of file descriptors,
|
||||
especially with Xwayland which can create a lot of pixmaps on behalf of
|
||||
its X11 clients.
|
||||
|
||||
For platforms where mremap() is available, keeping those file
|
||||
descriptors opened is a bit of a waste and may cause exhaustion of file
|
||||
descriptors sooner that before commit 5a981ee8.
|
||||
|
||||
Only keep the mmap() file descriptor open on platforms which do not
|
||||
implement mremap() and close it immediately as before on others.
