int32_t glue::PageCacheTracker::Entry::idx_stat

Points into the list of stat structs; >= 0 only for open files.

Definition at line 946 of file glue_buffer.h.

Referenced by glue::PageCacheTracker::Close(), glue::PageCacheTracker::GetInfoIfOpen(), and glue::PageCacheTracker::Open().

int32_t glue::PageCacheTracker::Entry::nopen

Reference counter for currently open files with a given inode. If the sign bit is set, the entry is in the transition phase from one hash to another. The sign will be cleared on Close() in this case.
