📄 Description

Relevant Issue (if applicable)

Details

When situations such as out of memory (OOM) occur, s3fs may receive a SIGKILL signal and exit before cleaning up the mountpoint. At this time, a stale mount point will be left, causing an error to be reported the next time s3fs is mounted: Transport endpoint is not connected.

This patch adds a feature: before s3fs mount, check if the stat information of the mountpoint returns ENOTCONN error, if so, it will execute the umount operation to unmount the stale mountpoint.
